AP Unit 3 respiration warm up

Front

What is glycolysis?

Back

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

Front

What is the input of glycolysis?

Back

Glucose

Front

What is the main function of the Krebs Cycle?

Back

To complete the breakdown of glucose and produce electron carriers (NADH and FADH2) for the electron transport chain.

Front

Where does the Krebs Cycle take place?

Back

Mitochondrial matrix

Front

Which step of cellular respiration requires oxygen?

Back

Oxidative Phosphorylation

Front

What is oxidation in biological terms?

Back

Oxidation is the loss of electrons from a molecule.

Front

What is reduction in biological terms?

Back

Reduction is the gain of electrons by a molecule.

Front

What are the products of glycolysis?

Back

2 pyruvate, 2 ATP, and 2 NADH.

Front

What is the role of NADH in cellular respiration?

Back

NADH carries electrons to the electron transport chain, where they are used to generate ATP.

Front

What is the electron transport chain?

Back

A series of protein complexes in the inner mitochondrial membrane that transfer electrons and pump protons to create a proton gradient.
