Oxidative Phosphorylation

What is oxidative phosphorylation?

• Process of ATP production using energy from the electron transport chain

• Process of ATP production using energy from the citric acid cycle

• Process of ATP production using energy from glycolysis

• Process of ATP production using energy from photosynthesis

Where does oxidative phosphorylation occur in the cell?

• cytoplasm

• inner mitochondrial membrane

• nucleus

• cell membrane

What are the main components involved in oxidative phosphorylation?

What is the role of electron transport chain in oxidative phosphorylation?

• The electron transport chain transports protons and generates electrons for ATP synthesis.

• The electron transport chain transfers electrons and generates a proton gradient for ATP synthesis.

• The electron transport chain breaks down ATP to generate electrons and protons.

• The electron transport chain is responsible for converting glucose into ATP.

What is the final electron acceptor in oxidative phosphorylation?

• water

• oxygen

• glucose

• carbon dioxide

What is the role of ATP synthase in oxidative phosphorylation?

• ATP synthase breaks down ATP during oxidative phosphorylation.

• ATP synthase synthesizes ATP during oxidative phosphorylation.

• ATP synthase is not involved in oxidative phosphorylation.

• ATP synthase transports ATP out of the cell during oxidative phosphorylation.

What is the difference between oxidative phosphorylation and substrate-level phosphorylation?

• Oxidative phosphorylation occurs in the cytoplasm and involves the direct transfer of a phosphate group from a substrate molecule to ADP.

• Substrate-level phosphorylation occurs in the mitochondria and involves the transfer of electrons from NADH and FADH2 to the electron transport chain.

• Oxidative phosphorylation and substrate-level phosphorylation are the same process with different names.

• Oxidative phosphorylation occurs in the mitochondria and involves the transfer of electrons from NADH and FADH2 to the electron transport chain, while substrate-level phosphorylation occurs in the cytoplasm and involves the direct transfer of a phosphate group from a substrate molecule to ADP.

What is the net ATP production in oxidative phosphorylation?

• 10-12

• 15-18

• 20-22

• 28-30

What are the inhibitors of oxidative phosphorylation?

• glucose, ATP, and NADH

• oxygen, water, and carbon dioxide

• acetyl-CoA, citrate, and malate

• cyanide, carbon monoxide, and oligomycin

What are the consequences of impaired oxidative phosphorylation?

• Decreased ATP production, reduced energy levels, muscle weakness, organ dysfunction, metabolic disorders

• Increased ATP production, elevated energy levels, enhanced muscle strength, improved organ function, improved metabolic disorders

• No effect on ATP production, normal energy levels, no muscle weakness, normal organ function, no metabolic disorders

• Increased ATP production, increased energy levels, increased muscle strength, improved organ function, improved metabolic disorders
