AP Bio Insta-Review Topic 3.6*: Cellular Respiration

Front

What is the primary function of ATP in cellular respiration?

Back

ATP serves as the main energy currency of the cell, providing energy for various cellular processes.

Front

Where does the Krebs Cycle occur in eukaryotic cells?

Back

The Krebs Cycle takes place in the mitochondrial matrix.

Front

What process must occur before fermentation can take place?

Back

Glycolysis must occur before fermentation.

Front

List the main products of the Krebs Cycle.

Back

The main products of the Krebs Cycle are ATP, 3 NADH, FADH2, and 2 CO2.

Front

True or False: Prokaryotes perform an electron transport chain on their plasma membrane.

Back

True.

Front

What is glycolysis and where does it occur?

Back

Glycolysis is the process of breaking down glucose into pyruvate, occurring in the cytosol.

Front

What are the two main stages of cellular respiration?

Back

The two main stages are aerobic respiration (which includes the Krebs Cycle and electron transport chain) and anaerobic respiration (fermentation).

Front

What is the role of NADH and FADH2 in cellular respiration?

Back

NADH and FADH2 are electron carriers that transport electrons to the electron transport chain.

Front

What is oxidative phosphorylation?

Back

Oxidative phosphorylation is the process of ATP production that occurs in the electron transport chain, using energy from electrons.

Front

What is the significance of the electron transport chain?

Back

The electron transport chain is crucial for generating ATP through the transfer of electrons and the establishment of a proton gradient.
