To what does the term grana refer? A stack of thylakoid membrane structures. The term derived from the Greek root that means “bed” or “mattress” is.
Which of these is not a major photosynthetic pigment in plants *?
Which of these is NOT a major photosynthetic pigment in plants? Chlorophyll c is not a major photosynthetic pigment in plants.
Does Chemiosmotic ATP synthesis occurs in the cytosol of the cell?
Chemiosmotic ATP synthesis occurs in the cytosol of the cell. Photorespiration is the process by which light is used to release the stored energy in carbohydrate molecules to perform all work in plant cells.
What are the two main sets of reactions for photosynthesis?
There are two main stages of photosynthesis: the light-dependent reactions and the Calvin cycle.
What does the term Thylakoid refer to?
: any of the membranous disks of lamellae within plant chloroplasts that are composed of protein and lipid and are the sites of the photochemical reactions of photosynthesis.
What is the name of the enzyme that fixes co2?
Indeed the most important biological mechanism for fixing carbon dioxide is very inefficient which is very much down to one enzyme: ribulose‐1 5‐bisphosphate carboxylase/oxygenase or RuBisCo for short.
Do red algae have Phycobilins?
The red algae were the first lineage of organisms to have true chloroplasts derived from the endosymbiosis of a cyanobacterium and so they have the same pigments: chlorophyll a and phycobilins. In particular the red algae derive most of their coloring from a red phycobilin called phycoerythrin.
Which of these processes occurs in the cytosol?
What does glycolysis produce?
How many ATP are produced in glycolysis?
What is ADP and NADP?
ATP – Adenosine triphosphate. ADP – Adenosine diphosphate. NADP – Nicotinamide adenine dinucleotide phosphate. NADPH – The reduced form of NADP. In the Light Dependent Processes i.e Light Reactions the light strikes chlorophyll a in such a way as to excite electrons to a higher energy state.
What does green light do to plants?
What color is chlorophyll?
green color
Chlorophyll is a pigment that gives plants their green color and it helps plants create their own food through photosynthesis.Sep 13 2019
What is grana quizlet?
granum (plural grana) A stack of hollow disks formed of thylakoid membrane in a chloroplast. Grana are the sites where light energy is trapped by chlorophyll and converted to chemical energy during the light reactions of photosynthesis.
What is grana function?
Grana (plural of ‘granum’) are stacks of structures called thylakoids which are little disks of membrane on which the light-dependent reactions of photosynthesis take place. Stacked into grana the shape of the thylakoids allow for optimum surface area maximizing the amount of photosynthesis that can happen.
What is the difference between grana and thylakoid?
What is the main final product of the Calvin cycle?
glucose
The reactions of the Calvin cycle add carbon (from carbon dioxide in the atmosphere) to a simple five-carbon molecule called RuBP. The Calvin cycle reactions use chemical energy from NADPH and ATP that were produced in the light reactions. The final product of the Calvin cycle is glucose.Mar 5 2021
What is the final product of carbon fixation?
The final product of the Calvin cycle d-glyceraldehyde 3-phosphate is a simple 3-carbon sugar that serves as the premier feedstock for all bioorganic compounds. The net chemical reaction (7. R4) fixes 6 molecules of CO2 as carbon 1 in 6 molecules of d-glyceraldehyde 3-phosphate.
Why photosynthesis is called carbon assimilation?
Photosynthesis is the process by which plants prepare their food in the presence of sunlight using water and carbon dioxide as the raw materials. … So you see how a simple CO2 molecule is yielding a complex compound which is glucose. Thus we say it is a carbon assimilation or carbon collection process.
What is green algae called?
Chlorophyta are microorganisms that are grouped in the kingdom called Protista. The microbes are plant-like in that they are able to manufacture energy from sunlight. The microbes are also commonly known as green algae.
What light absorbs phycoerythrin?
What are carotenoids and phycobilins?
All carotenoids are tetraterpenoids meaning that they are produced from 8 isoprene molecules and contain 40 carbon atoms. Carotenoids in general absorb blue light. … The phycobilins are especially efficient at absorbing red orange yellow and green light wavelengths that are not well absorbed by chlorophyll a.
What reaction occurs in the cytosol?
Major metabolic pathways that occur in the cytosol in animals are protein biosynthesis the pentose phosphate pathway glycolysis and gluconeogenesis. The localization of pathways can be different in other organisms for instance fatty acid synthesis occurs in chloroplasts in plants and in apicoplasts in apicomplexa.
Which stage of cellular respiration takes place in the cytosol?
Glycolysis occurs in the cytosol of the cell and does not require oxygen whereas the Krebs cycle and electron transport occur in the mitochondria and do require oxygen.
What is the function of the cytosol?
Cytosol Functions
It is involved in signal transduction between the cell membrane and the nucleus and organelles. It transports metabolites from their production site to other parts of the cell. It is important for cytokinesis when the cell divides in mitosis. The cytosol plays a role in eukaryote metabolism.
What is the another name of glycolysis?
Complete step by step answer: The other name of glycolysis is the Embden–Meyerhof–Parnas (EMP) pathway because it was discovered by Gustav Embden Otto Meyerhof and Jakub Karol Parnas. The glycolysis is a metallic pathway that converts glucose into two molecules of pyruvate through a series of reactions.
What is glycolysis explain?
How do you draw glycolysis?
Does glycolysis produce co2?
Glucose ( 6 carbon atoms) is split into 2 molecules of pyruvic acid (3 carbons each). This produces 2 ATP and 2 NADH. Glycolysis takes place in the cytoplasm. This breaks down the pyruvic acid to carbon dioxide.
Is glycolysis aerobic or anaerobic?
Glycolysis (see “Glycolysis” concept) is an anaerobic process – it does not need oxygen to proceed. This process produces a minimal amount of ATP. The Krebs cycle and electron transport do need oxygen to proceed and in the presence of oxygen these process produce much more ATP than glycolysis alone.
What is Pi in glycolysis?
The second step of glycolysis involves the conversion of glucose-6-phosphate to fructose-6-phosphate (F6P). This reaction occurs with the help of the enzyme phosphoglucose isomerase (PI). … The reaction involves the rearrangement of the carbon-oxygen bond to transform the six-membered ring into a five-membered ring.
What is AMP biology?
Adenosine monophosphate (AMP) is one of the components of RNA and also the organic component of the energy-carrying molecule ATP. In certain vital metabolic processes AMP combines with inorganic phosphate to form ADP (adenosine diphosphate) and then ATP.
What are the Assimilatory power?
Assimilatory power is the power of plants in the form of ATP & NADPH (produce during light reactions) to obtain food in the form of carbohydrates from the reduction of CO2 during photosynthesis.
What is the difference between ATP and NADPH?
Grana refers to
Grana present in chloroplast refers to
