**Energy & Enzymes**

Front

What is the role of enzymes in chemical reactions?

Back

Enzymes act as catalysts that speed up chemical reactions without being consumed in the process.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds between molecules of matter.

Front

What are the products in a chemical reaction?

Back

Products are the substances that are formed as a result of a chemical reaction.

Front

True or False: An enzyme can be used multiple times in chemical reactions.

Back

True. Enzymes can be used repeatedly as they are not consumed in the reaction.

Front

What is a catalyst?

Back

A catalyst is a substance that speeds up a chemical reaction without being permanently altered.

Front

What factors can affect enzyme activity?

Back

Factors include temperature, pH, substrate concentration, and the presence of inhibitors or activators.

Front

What is the active site of an enzyme?

Back

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

Front

How do temperature changes affect enzyme activity?

Back

Increased temperature generally increases enzyme activity up to a certain point, after which the enzyme may denature and lose function.

Front

What is enzyme specificity?

Back

Enzyme specificity refers to the ability of an enzyme to select and catalyze a specific substrate.

Front

What is the difference between competitive and non-competitive inhibitors?

Back

Competitive inhibitors bind to the active site of an enzyme, while non-competitive inhibitors bind to a different site, altering enzyme function.
