Is the major function of DNA to provide the genetic instructions for protein synthesis?

The major function of DNA is to provide the genetic instructions for protein synthesis. DNA provides the basic instructions for building every protein in the body. RNA carries out the orders for protein synthesis issued by DNA.

What is the primary energy transferring molecule in cells What is the primary energy transferring molecule in cells carbohydrates ATP RNA DNA?

ATP: fueling chemical reactions. Adenosine triphosphate or ATP is the primary carrier of energy in cells. The water-mediated reaction known as hydrolysis releases energy from the chemical bonds in ATP to fuel cellular processes.

What is the energy molecule for the cell?

Adenosine 5′-triphosphate or ATP is the most abundant energy carrier molecule in cells. This molecule is made of a nitrogen base (adenine) a ribose sugar and three phosphate groups.

What is primary active transport quizlet?

Primary Active Transport. *Transport of molecules across the membrane AGAINST a CONCENTRATION GRADIENT.

What is the energy molecule of the cell called quizlet?

Adenosine triphosphate or ATP for short is the energy currency of life. ATP is a high-energy molecule found in every cell. Its job is to store and supply the cell with needed energy.

Which of the following is a primary function of molecule B?

Which of the following is a primary function of molecule B? energy storage: The hydrocarbon groups that dominate the structure of triglycerides are the basis for the efficient and compact energy storage by fat.

What energy carrying molecule is created in this process?


ATP is the energy-carrying molecule produced by the mitochondria through a series of chemical reactions. The more active a cell (such as a muscle cell) the more mitochondria it will have.

Why is glucose the primary energy source for cells?

Glucose is the most important substrate of cell metabolism. It is the carbohydrate fulfilling the task of being the energy transport system of the body. Several parts of the body like the nervous system or blood cells are completely dependent on glucose as the supplier of energy.

Which process can produce the most energy for a cell?

cell respiration

Eukaryotic cells use their mitochondria to generate ATP through a process called cell respiration. Respiration that uses oxygen is called aerobic respiration while oxygen-less respiration is called anaerobic respiration.

What part of DNA provides instructions for making proteins?

Each DNA sequence that contains instructions to make a protein is known as a gene. The size of a gene may vary greatly ranging from about 1 000 bases to 1 million bases in humans. Genes only make up about 1 percent of the DNA sequence.

What do you call the process which converts the instructions in the DNA into a functional biological product called protein?

Gene expression
Gene expression is the process by which the instructions in our DNA are converted into a functional product such as a protein.Jul 21 2021

Is the transfer of genetic instructions in DNA to mRNA?

Transcription is the first part of the central dogma of molecular biology: DNA → RNA. It is the transfer of genetic instructions in DNA to messenger RNA (mRNA). During transcription a strand of mRNA is made that is complementary to a strand of DNA.

How many phosphates does ADP have?

two phosphate

ADP consists of three important structural components: a sugar backbone attached to adenine and two phosphate groups bonded to the 5 carbon atom of ribose.

Does ATP have ribose or deoxyribose?

A DNA nucleotide contains the sugar deoxyribose whereas an ATP molecule contains the sugar ribose. As for the nitrogenous base ATP can only contain the base adenine whereas a DNA nucleotide can have 4 different bases.

How is energy stored in the ATP molecule?

Energy is stored in the covalent bonds between phosphates with the greatest amount of energy (approximately 7 kcal/mole) in the bond between the second and third phosphate groups. This covalent bond is known as a pyrophosphate bond.

How the food is converted into ATP molecules to be used by the cells?

Through the process of cellular respiration the energy in food is converted into energy that can be used by the body’s cells. During cellular respiration glucose and oxygen are converted into carbon dioxide and water and the energy is transferred to ATP.

What type of energy transformation takes place in photosynthesis?

chemical energy

Photosynthesis is the process by which energy is converted to chemical energy in plant cells. In cellular respiration plants use the chemical energy stored during photosynthesis in basic life processes.

How does ADP get converted to ATP?

ADP is converted to ATP for the storing of energy by the addition of a high-energy phosphate group. The conversion takes place in the substance between the cell membrane and the nucleus known as the cytoplasm or in special energy-producing structures called mitochondria.

What is primary and secondary active transport?

In primary active transport the energy is derived directly from the breakdown of ATP. … In the secondary active transport the energy is derived secondarily from energy that has been stored in the form of ionic concentration differences between the two sides of a membrane.

What happens in primary active transport?

Primary active transport also called direct active transport directly uses chemical energy (such as from adenosine triphosphate or ATP in case of cell membrane) to transport all species of solutes across a membrane against their concentration gradient.

What do primary and secondary active transport have in common?

Similarities Between Primary and Secondary Active Transport

Both methods are involved in the pumping of molecules against the concentration gradient from a low concentration to a high concentration.

Which is the primary molecule broken down for energy in cells quizlet?

Carbohydrates are the molecules most commonly broken down to make ATP. However lipids store the most energy. When fats are broken down they yield the most ATP.

Is a molecule that transfers energy from the breakdown of food molecules to cell processes?

Your energy does come from food but not directly. All cells like that in Figure 1.1 use chemical energy carried by ATP— adenosine triphosphate. ATP is a molecule that transfers energy from the breakdown of food molecules to cell processes. You can think of ATP as a wallet filled with money.

What is the key component of the energy molecule ATP?

Phosphorous is a key component of the energy molecule of ATP.

Which of the following is the primary function of lipids?

Synthesis and Function of Lipids in the Body

See also what is the source of energy for all living things

The main biological functions of lipids include storing energy as lipids may be broken down to yield large amounts of energy. Lipids also form the structural components of cell membranes and form various messengers and signaling molecules within the body.

What are the four major categories of macromolecules describe the basic structures and the primary functions of each?

  • Nucleic acids: Stores and transfers info.
  • Carbohydrates Store energy provide fuel and build structure in body main source of energy structure of plant cell wall.
  • Lipid: Insulator and stores fat and energy.
  • Protein: Provide structural support transport enzymes movement defense.

What determines the primary structure of a protein?

The primary structure of a protein — its amino acid sequence — drives the folding and intramolecular bonding of the linear amino acid chain which ultimately determines the protein’s unique three-dimensional shape. … Folded proteins are stabilized by thousands of noncovalent bonds between amino acids.

What process of energy conversion takes place in the mitochondria?

Mitochondria using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. The process is called oxidative phosphorylation and it happens inside mitochondria.

What are the energy-carrying molecules involved in cellular respiration?

Name three energy-carrying molecules involved in cellular respiration. During cellular respiration NADH and ATP are used to make glucose. ATP synthase acts as both an enzyme and a channel protein. The carbons from glucose end up in ATP molecules at the end of cellular respiration.

What are the energy-carrying molecules produced during cellular respiration?

During cellular respiration glucose is broken down in the presence of oxygen to produce carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).
