What is the role of NADPH in photosynthesis?

Back

NADPH is produced in the light-dependent reactions and is used in the Calvin Cycle (light-independent reactions) to reduce carbon dioxide into glucose.

Front

What happens to water during the light-dependent reactions?

Back

Water is oxidized to produce oxygen, protons, and electrons, which are essential for the production of ATP and NADPH.

Front

What is the function of pigments in photosynthesis?

Back

Pigments absorb light energy, which is then converted into chemical energy during the light-dependent reactions.

Front

What is glycolysis?

Back

Glycolysis is the metabolic pathway that converts glucose into pyruvate, producing a net gain of 2 ATP and 2 NADH.

Front

What are the byproducts of fermentation?

Back

Fermentation produces byproducts such as lactic acid or ethanol and carbon dioxide, depending on the type of fermentation.

Front

What is the main product of the Calvin Cycle?

Back

The main product of the Calvin Cycle is glucose, which is synthesized from carbon dioxide using ATP and NADPH.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the process by which ATP is produced using the energy released from the electron transport chain and the proton gradient.

Front

What is the difference between aerobic and anaerobic respiration?

Back

Aerobic respiration requires oxygen and produces more ATP, while anaerobic respiration occurs without oxygen and produces less ATP.

Front

What is the significance of the citric acid cycle?

Back

The citric acid cycle (Krebs cycle) is crucial for the oxidation of acetyl-CoA, producing NADH, FADH2, and ATP, which are used in oxidative phosphorylation.

Front

What is the role of ATP in cellular processes?

Back

ATP serves as the primary energy currency of the cell, providing energy for various biochemical reactions.
