Front

What is reduction in a chemical context?

Back

Reduction is the process in which a molecule gains electrons.

Front

Where is ATP synthase located in cellular respiration?

Back

ATP synthase is located in the inner mitochondrial membrane.

Front

Which metabolic process does NOT require oxygen?

Back

Glycolysis does not require oxygen.

Front

How does an enzyme speed up a reaction?

Back

An enzyme speeds up a reaction by binding to and stabilizing the transition state, which decreases the activation energy.

Front

What is the sequence of electron flow during aerobic respiration?

Back

Electrons travel from food to NADH, then to the electron transport chain, and finally to oxygen.

Front

Define glycolysis.

Back

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

Front

What is the role of NADH in cellular respiration?

Back

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

Front

What is the function 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 the Krebs Cycle also known as?

Back

The Krebs Cycle is also known as the Citric Acid Cycle.

Front

What is the main purpose of aerobic respiration?

Back

The main purpose of aerobic respiration is to produce ATP through the oxidation of glucose.
