AP Biology - Unit 3 Review

Front

The amount of energy needed for a reaction to occur is called the _________.

Back

activation energy

Front

Which of the following is NOT produced during the electron transport chain in cellular respiration?

Back

ATP

Front

Between which parts of the molecule must the bonds be broken to form an ADP molecule?

Back

C and D

Front

The place, other than the active site, where activators and inhibitors bind to an enzyme is called the ________ site.

Back

allosteric

Front

Chemiosmosis is best described as...

Back

The use of a proton gradient to power ATP Synthase and produce ATP

Front

What is the primary function of ATP in cellular processes?

Back

ATP serves as the main energy currency of the cell.

Front

Define the term 'enzyme'.

Back

An enzyme is a biological catalyst that speeds up chemical reactions in cells.

Front

What role do electron carriers play in cellular respiration?

Back

Electron carriers transport electrons from one reaction to another, facilitating energy transfer.

Front

What is the significance of the proton gradient in cellular respiration?

Back

The proton gradient is essential for ATP synthesis during oxidative phosphorylation.

Front

What is the difference between competitive and allosteric inhibition?

Back

Competitive inhibition occurs when an inhibitor competes with the substrate for the active site, while allosteric inhibition occurs when an inhibitor binds to a site other than the active site, changing the enzyme's shape.
