Where do food molecules come from?

The energy content of all food molecules can be traced back to the Sun. It is the process of photosynthesis that locks the Sun’s energy into simple carbohydrates like glucose.

What type of energy comes from food?

Food energy is chemical energy that animals (including humans) derive from their food and molecular oxygen through the process of cellular respiration.

What is the energy from food called?


The source of the energy required to regenerate ATP is the chemical energy stored in food (e.g. glucose). The cellular process of releasing energy from food through a series of enzyme-controlled reactions is called respiration . Some of the energy released is used to produce ATP.

How is the energy in food released by the human body?

When the stomach digests food the carbohydrate (sugars and starches) in the food breaks down into another type of sugar called glucose. The stomach and small intestines absorb the glucose and then release it into the bloodstream.

Which process releases most energy?

Solution: The first stages of respiration occur in the cytoplasm but most of the energy released is in the mitochondria (the powerhouse of the cell). During aerobic respiration 38 ATP molecules of chemical energy are produced.

How is energy formed in a cell?

Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis glycolysis the citric acid cycle and oxidative phosphorylation.

What is the source of most food energy?

The Sun

3.1 The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants algae and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.

Where do the atoms in the food molecules go?

Where do the atoms in the food molecules go? The atoms become carbon dioxide and water. Carbon dioxide and water leave the body by breathing.

How does the body release energy?

Your body cells use the oxygen you breathe to get energy from the food you eat. This process is called cellular respiration. During cellular respiration the cell uses oxygen to break down sugar. … When the cell uses oxygen to break down sugar oxygen is used carbon dioxide is produced and energy is released.

Where does the energy in food come from quizlet?

Energy in most food comes from the sun. What is one of the principal chemical compounds that living things use to store energy? Adenosine triphosphate or ATP.

How does food yield energy?

The food produced through the photosynthesis converted into glucose and then into starch which is used by the plant for various purposes for like growth. When humans and animals eat food through the process of metabolism it is converted into energy and transferred into cell for their process.

How is energy captured and carried in cells?

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).

Which of the following is usually used by the cell for the production of energy?

Answer: 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 the main source of energy for the body?

Carbohydrates are the body’s main source of energy. The fruit vegetables dairy and grain food groups all contain carbohydrates. Sweeteners like sugar honey and syrup and foods with added sugars like candy soft drinks and cookies also contain carbohydrates.

Which process releases the most energy in the form of ATP?

the Krebs cycle

The process which produces the most energy in the form of ATP is the Krebs cycle- also known as the citric acid cycle.

Which process depends on energy from respiration?

Respiration releases energy – it is an exothermic process. … Photosynthesis is the process by which plants and some bacteria synthesise food molecules – which they then use in addition to other things for respiration. The process of photosynthesis requires energy – it is endothermic .

Which process releases the most ATP per molecule of glucose for immediate cell use?

oxidative phosphorylation

So oxidative phosphorylation is the metabolic cycle that produces the most net ATP per glucose molecule.

Where is energy produced in cell?

In eucaryotes these reactions all take place in mitochondria the organelle to which pyruvate and fatty acids are directed for acetyl CoA production (Figure 2-78). We should therefore not be surprised to discover that the mitochondrion is the place where most of the ATP is produced in animal cells.

What part of the cell stores energy?

ATP is how cells store energy. These storage molecules are produced in the mitochondria tiny organelles found in eukaryotic cells sometimes called the “powerhouse” of the cell.

What converts food into energy in plant and animal cells?

Animal cells use mitochondria to convert food into energy and plant cells use both chloroplasts and mitochondria to make energy from light air and water.

What is the source of energy in the food molecule?

Glucose found in the food animals eat is broken down during the process of cellular respiration into an energy source called ATP. When excess ATP and glucose are present the liver converts them into a molecule called glycogen which is stored for later use.

How does a food molecule travel through a cell?

Nutrients that are Absorbed by Diffusion

Water and other tiny molecules move through the pores in cells. … Fructose moves through facilitated diffusion using a carrier protein to get across the cell membrane. Glucose on the other hand moves through active transport.

How does food get into cells?

We need to eat and drink to survive and so do our cells. Using a process called endocytosis cells ingest nutrients fluids proteins and other molecules. … During endocytosis the cell membrane curves inward essentially forming a mouth to engulf ingestible cargo.

Where do food molecules for Cecropia trees come from?

Explanation: Food molecules for cecropia trees come from Central and South American forests…..

How is ATP energy produced?

ATP is a nucleotide consisting of an adenine base attached to a ribose sugar which is attached to three phosphate groups. … When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis energy is released and ATP is converted to adenosine diphosphate (ADP).

Where does the energy in food originally come from ATP?

Cells contain only a small amount of ATP at any one time. They create new ATP molecules from ADP as they need it using the energy stored in food (glucose) to add that third phosphate. Heterotrophs and Autotrophs The energy to make ATP from ADP comes from food (glucose).

Which process releases energy for the cell quizlet?

Cellular respiration requires a food molecules such as of glucose and oxygen and gives off carbon water and energy.

Where does the energy in food originally come from Explain your answer?

The energy in food is originally derived from sunlight. Sunlight is the catalyst for photosynthesis in plants in which carbon dioxide and water are…

Where is ATP produced in the cell?

Most of the ATP in cells is produced by the enzyme ATP synthase which converts ADP and phosphate to ATP. ATP synthase is located in the membrane of cellular structures called mitochondria in plant cells the enzyme also is found in chloroplasts.Oct 4 2021

Where does cellular respiration occur?

While most aerobic respiration (with oxygen) takes place in the cell’s mitochondria and anaerobic respiration (without oxygen) takes place within the cell’s cytoplasm.
