AP Biology: Unit 3 Review (CED)

Front

What are the main electron carriers in the electron transport chain during cellular respiration?

Back

NADH and FADH2 are the main electron carriers in the electron transport chain.

Front

What must occur to maintain order and power cellular processes?

Back

Energy input must exceed energy loss to maintain order and power cellular processes.

Front

Where did photosynthesis first evolve?

Back

Photosynthesis first evolved in prokaryotic organisms.

Front

Which metabolic process does NOT require oxygen?

Back

Glycolysis does not require oxygen.

Front

What is the difference between competitive and noncompetitive inhibitors?

Back

Competitive inhibitors bind to the active site, while noncompetitive inhibitors bind to a different site.

Front

Define cellular respiration.

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

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.

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 Krebs Cycle?

Back

The Krebs Cycle, also known as the citric acid cycle, is a series of chemical reactions used by all aerobic organisms to generate energy through the oxidation of acetyl-CoA.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the final stage of cellular respiration, where ATP is produced using energy derived from the electron transport chain.
