24-25 Enzymes and Energy Cycle

What is the function of an enzyme?

• Enzymes help in the formation of cellular organelles.

• The function of an enzyme is to speed up chemical reactions inside cells..

• Enzymes are responsible for transporting nutrients in the bloodstream.
• Enzymes are used to store energy in cells.

Which of the following factors can affect enzyme activity?

• Temperature and pH levels.

• Only the concentration of substrates.

• The color of the enzyme.

• The size of the enzyme.

What is the role of the active site in an enzyme?

• The active site is where substrates bind and undergo a chemical reaction.

• The active site is where enzymes are stored for future use.

• The active site is responsible for the enzyme's color.

• The active site is where enzymes are synthesized.

Which of the following best describes how matter is conserved through cellular respiration and photosynthesis?

• Matter is created during cellular respiration and destroyed during photosynthesis.

• Matter is only conserved in photosynthesis, not in cellular respiration.
• The number of carbon, hydrogen and oxygen atoms is the same in both the products and reactants.

• Matter is lost as energy during the processes of respiration and photosynthesis.
