Unit 3 AP Biology Insta-Review (Cellular Energetics)

Front

Where does the electron transport chain of cellular respiration occur?

Back

Cristae

Front

What is an inhibitor that binds to the active site of an enzyme?

Back

Competitive inhibitor

Front

When an enzyme denatures, which structure is not affected?

Back

Primary structure

Front

What happens to the reaction rate if the enzyme is denatured?

Back

Reaction rate decreases

Front

Which law states that every reaction increases the entropy of the universe?

Back

Second law of thermodynamics

Front

What is the primary function of the electron transport chain?

Back

To produce ATP through oxidative phosphorylation.

Front

What is the role of ATP in cellular processes?

Back

ATP serves as the primary energy currency of the cell.

Front

Define denaturation in the context of enzymes.

Back

Denaturation is the process where an enzyme loses its functional shape due to external stress, affecting its activity.

Front

What is the difference between competitive and noncompetitive inhibitors?

Back

Competitive inhibitors bind to the active site, while noncompetitive inhibitors bind to another part of the enzyme.

Front

What is the significance of the primary structure of a protein?

Back

The primary structure determines the protein's unique sequence of amino acids, which influences its overall shape and function.
