Cellular Respiration Honors Bio

Front

What is the main function of ATP synthase in cellular respiration?

Back

ATP synthase is an enzyme that synthesizes ATP from ADP and inorganic phosphate during oxidative phosphorylation in the electron transport chain.

Front

What are the two main parts of the mitochondria involved in cellular respiration?

Back

The inner membrane and the outer membrane.

Front

What is the role of the inner membrane of the mitochondria?

Back

The inner membrane contains the electron transport chain and ATP synthase, which are crucial for ATP production.

Front

What is the matrix of the mitochondria?

Back

The matrix is the innermost compartment of the mitochondria, where the Krebs cycle occurs and contains enzymes, mitochondrial DNA, and ribosomes.

Front

What is the source of carbon and oxygen released during the Krebs cycle?

Back

The carbon and oxygen are derived from glucose, which is broken down during cellular respiration.

Front

What is the purpose of the electron transport chain?

Back

The electron transport chain transfers electrons from NADH and FADH2 to oxygen, creating a proton gradient that drives ATP synthesis.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the process of ATP production that occurs in the mitochondria, involving the electron transport chain and ATP synthase.

Front

What is the role of NADH in cellular respiration?

Back

NADH acts as an electron carrier, transporting electrons to the electron transport chain for ATP production.

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 are the end products of the Krebs cycle?

Back

The end products of the Krebs cycle include carbon dioxide, ATP, NADH, and FADH2.
