DC Biology SA Review 1 Flashcard

Front

What is the role of ATP synthase in photosynthesis?

Back

ATP synthase is an enzyme that facilitates the production of ATP from ADP and inorganic phosphate by utilizing the proton gradient created in the thylakoid space.

Front

What is the expected percentage of Thymine in a DNA sample if the percentage of Adenine is 22%?

Back

22% Thymine, as Adenine pairs with Thymine in DNA.

Front

What are the products formed in one turn of the Krebs cycle?

Back

1 ATP, 3 NADH, 1 FADH2, and 2 CO2.

Front

What is the function of NADPH in photosynthesis?

Back

NADPH acts as a short-term energy carrier, providing reducing power for the synthesis of glucose during the Calvin cycle.

Front

What is the net gain of ATP during glycolysis?

Back

The net gain of ATP during glycolysis is 2 ATP.

Front

What is glycolysis?

Back

Glycolysis is the metabolic pathway that converts glucose into pyruvate, producing a small amount of ATP and NADH.

Front

What is the significance of the proton gradient in cellular respiration?

Back

The proton gradient is essential for ATP production, as it drives ATP synthase to convert ADP into ATP.

Front

What are the light-dependent reactions of photosynthesis?

Back

The light-dependent reactions convert solar energy into chemical energy in the form of ATP and NADPH.

Front

What is the difference between NADH and NADPH?

Back

NADH is primarily involved in energy production during cellular respiration, while NADPH is used in anabolic reactions, such as the Calvin cycle.

Front

What is the role of FADH2 in cellular respiration?

Back

FADH2 is an electron carrier that donates electrons to the electron transport chain, contributing to ATP production.
