Enyzmes are a very important type of protein used to

• Build bones in skeleton
• Send hormonal signals throughout body
• Speed up chemical reactions
• Photosynthesize glucose in plants

What is the monomer of proteins?

• amino acids

• fatty acids

• monosaccharides

Enzymes are capable of increasing the rate of a chemical reaction within a living cell.  Enzymes accomplish this through which of the following means?

Given the graph below, which statement best describes the role of enzymes?

• More energy is released without the presence of enzymes
• Less energy is needed to start a reaction when enzymes are present.
• A reaction is catalyzed by the lack of enzymes
• The presence of enzymes causes reactions to occur at a slower rate.

What is being represented by the letter A in the image?

• Substrate
• Enzyme
• Product
• Complex

Amino acids that must be supplied by foods in the diet

• essential amino acid
• complete protein
• emulsion
• collagen

Each amino acid is different from the other due to....

• The R group
• The amino group
• The carboxyl group
• The central carbon

Cells must produce many different enzymes because

• enzymes are quickly used up
• most cellular reactions require a specific, unique enzyme
• They have to have some way to use up the protein that they consume
• enzymes are not very effective at speeding up reactions

Enzymes speed up a reaction by

• lowering activation energy
• increasing temperature
• creating more reactants
• increasing activation energy
