AP Biology: Unit 3 Review (CED)

Front

What environmental conditions can cause denaturation of an enzyme?

Back

Extreme increase in temperature and pH changes.

Front

Which structure of a protein is unaffected by denaturation?

Back

Primary structure.

Front

Describe the pathway of electrons in the light reactions of photosynthesis.

Back

H₂O → PSII → ETC → PSI → NADPH.

Front

What will increase the rate of a biochemical reaction?

Back

Increase enzyme concentration.

Front

What is the effect on free energy when the amount of enzyme is doubled?

Back

No effect on free energy.

Front

Define denaturation in the context of enzymes.

Back

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

Front

What is the primary structure of a protein?

Back

The sequence of amino acids in a polypeptide chain.

Front

What role does pH play in enzyme activity?

Back

pH can affect the ionization of amino acids, altering enzyme shape and function.

Front

What is the function of the electron transport chain (ETC) in photosynthesis?

Back

To transfer electrons and create a proton gradient for ATP synthesis.

Front

What is the significance of NADPH in photosynthesis?

Back

NADPH is used as a reducing agent in the Calvin cycle to convert carbon dioxide into glucose.
