Which compound is a metabolic intermediate?
Acetaldehyde Acetaldehyde is a metabolic intermediate in humans. It has been identified in food, beverages, and cigarette smoke. Acetaldehyde is metabolized primarily in the liver to a lesser extent in renal tubules by acetaldehyde dehydrogenase.
Which is required for the light-independent reactions in photosynthesis?
The ultimate goal of the light-independent reactions (or Calvin cycle) is to assemble a molecule of glucose. This is the part of photosynthesis that requires the CO2 the plant gets from the air. Essentially, the plant needs the carbon from the CO2 to create the building blocks for glucose.
What is one role of ATP in the light-independent reaction of photosynthesis quizlet?
What is one role of ATP in the light-independent reaction of photosynthesis? ATP supplies the energy to produce glucose and other carbohydrates.
What is meant by metabolic intermediate?
Metabolic intermediates are molecules that are the precursors or metabolites of biologically significant molecules. Although these intermediates are of relatively minor direct importance to cellular function, they can play important roles in the allosteric regulation of enzymes.
Is oxygen light dependent or independent?
Explanation: Oxygen is in fact a by product of light dependent reactions of photosynthesis. During light reaction of photosynthesis, In non-cyclic electron flow, when Photosystem II absorbs light, an electron is excited to a higher energy level in the reaction center of Chlorophyll P680 .
Is glucose a metabolic intermediate?
Intermediates. Glucose and fructose are the sugar 'funnels' serving as entry points to the glycolytic pathway. Other sugars must be converted to either of these forms to be directly metabolized.
What are the two intermediates of metabolism?
In the last few years it has become evident that small metabolic intermediates can be common denominators between two elementary biological processes: energy metabolism and gene regulation.
Which compound is a metabolic intermediate of the light dependent?
ATP and NADPH are produced in the light-dependent reactions and used in the light-independent reactions.
What are the products of light-independent reactions?
The products of the light independent reaction are glucose, NADP+, and H2O. The reactants are CO2, NADPH, and ATP.
Which compound is a metabolic intermediate of the light-dependent?
ATP and NADPH are produced in the light-dependent reactions and used in the light-independent reactions.
What occurs during the light-independent reactions of photosynthesis quizlet?
What happens during the light-independent reactions? During the light-independent reactions, ATP and NADPH from the light-dependent reactions are used to produce high-energy sugars.
What is light-independent in photosynthesis?
Light-independent reaction is a series of biochemical reactions in photosynthesis not requiring light to proceed, and ultimately produce organic molecules from carbon dioxide. The energy released from ATP (produced during the light reactions) drives this metabolic pathway.
What is NADPH in photosynthesis?
NADPH stands for Nicotinamide Adenine Dinucleotide PHosphate. It is formed by a series of reactions between Vitamin B3 and a sugar and a phosphate plus ATP and an extra hydrogen to make up NADPH.
What is a major metabolic intermediate?
Metabolic intermediates are molecules that are the precursors or metabolites of biologically significant molecules. Although these intermediates are of relatively minor direct importance to cellular function, they can play important roles in the allosteric regulation of enzymes.
Which of the following occurs in the light-independent reactions of photosynthesis quizlet?
The light-independent reactions turn glucose, a sugar, into CO2 gas. The light-independent reactions use CO2 to make ATP. The light-independent reactions turn sugar into ATP for energy.
Which molecules are produced during the light reactions of photosynthesis?
The light-dependent reactions use light energy to make two molecules needed for the next stage of photosynthesis: the energy storage molecule ATP and the reduced electron carrier NADPH.
What are products of light-independent reactions?
The products of the light independent reaction are glucose, NADP+, and H2O. The reactants are CO2, NADPH, and ATP.
What are the 3 products of the light-independent reactions?
The three products of light reaction of photosynthesis are ATP, NADPH and O2.
What is the product of light-independent reaction?
The light-independent reaction's reactants are carbon dioxide, NADPH and ATP. Its products are glucose, NADP+, ADP, and inorganic phosphate.
What is NADPH and NADP in photosynthesis?
During these light-dependent reactions of photosynthesis, a chemical called NADP (nicotinamide adenine dinucleotide phosphate) picks up two hydrogen atoms from water molecules forming NADPH2, a powerful reducing agent that is used to convert carbon dioxide into glucose during the dark reactions of photosynthesis (also …
Which of the following describes the light-dependent and light-independent reactions of photosynthesis?
Which of the following statements best describes the relationship between the light-dependent and light-independent reactions of photosynthesis? The light-independent reactions release energy, and the light-dependent reactions require energy.
Which of the following are products of the light-dependent reactions of photosynthesis that are required by reactions in the Calvin cycle?
The light reactions provide ATP and NADPH to the Calvin cycle, and the cycle returns ADP, Pi, and NADP+ to the light reactions.
Which of the following molecules is produced in the light-independent reactions?
Light reactions harness energy from the sun to produce chemical bonds, ATP, and NADPH. These energy-carrying molecules are made in the stroma where carbon fixation takes place.
What is light independent in photosynthesis?
Light-independent reaction is a series of biochemical reactions in photosynthesis not requiring light to proceed, and ultimately produce organic molecules from carbon dioxide. The energy released from ATP (produced during the light reactions) drives this metabolic pathway.
What are the products of the light-independent reactions quizlet?
The products of light-dependent pathways of photosynthesis are Oxygen, ATP, and NADPH. The reactants of light-independent reactions are ATP, NADPH, and Carbon Dioxide. The main purpose of the light independent reaction is to produce glucose.
Is glucose light-dependent or independent?
The light-independent reactions use the ATP and NADPH from the light-dependent reactions to reduce carbon dioxide and convert the energy to the chemical bond energy in carbohydrates such as glucose.
Is glucose a product of light-independent reactions?
The light-independent reactions use the ATP and NADPH from the light-dependent reactions to reduce carbon dioxide and convert the energy to the chemical bond energy in carbohydrates such as glucose.
What is the function of NAD+ and NADP?
NAD and NADP are the most abundant coenzymes in the cells, which are used in oxidation-reduction reactions. Both NAD and NADP are structurally similar but, NADP contains a phosphate group. NAD is mainly used in the cellular respiration and electron transport chain whereas NADP is used in the photosynthesis.
Where do light-independent reactions occur during photosynthesis?
Photosynthesis occurs in the chloroplasts, the light-dependent reactions are located on the innermost membrane of chloroplasts called thylakoid membrane and light-independent reactions occur in the cytoplasm of the chloroplasts called stroma (17).
