AP Biology: Unit 3 Review (CED)

Front

What effect does an increase in temperature have on the rate of a chemical reaction?

Back

An increase in temperature increases the speed/kinetic energy of particles, leading to more frequent collisions and a higher reaction rate.

Front

What environmental conditions can cause denaturation of enzymes?

Back

Extreme increase in temperature and pH changes can cause denaturation of enzymes.

Front

Which protein structure is unaffected by denaturation?

Back

The primary structure of a protein is unaffected by denaturation.

Front

Where does the electron transport chain occur in eukaryotic cells?

Back

The electron transport chain occurs in the mitochondria.

Front

What are the products of the light-dependent reactions of photosynthesis?

Back

The products are NADPH and ATP.

Front

Define denaturation in the context of proteins.

Back

Denaturation is the process where proteins lose their native structure due to external stress, such as temperature or pH changes.

Front

What is the role of enzymes in biological reactions?

Back

Enzymes act as catalysts to speed up chemical reactions by lowering the activation energy.

Front

What is the primary structure of a protein?

Back

The primary structure is the linear sequence of amino acids in a polypeptide chain.

Front

What is the function of ATP in cellular processes?

Back

ATP serves as the primary energy currency of the cell, providing energy for various biochemical reactions.

Front

What is the significance of the active site of an enzyme?

Back

The active site is the region on the enzyme where substrate molecules bind and undergo a chemical reaction.
