Biochemistry Review

What are the building blocks of proteins?

• Simple Sugars

• Fatty Acid and Glycerol

• Amino Acids

• Nucleotides

What are the building blocks of carbohydrates?

• Simple Sugars

• Fatty Acid and Glycerol

• Amino Acids

• Nucleotides

What factor or factors affect how enzymes function?

• Temperature

• Amount of a substance

• pH

• None of the above

The function of a specific enzyme is most directly influenced by its

• molecular size

• physical shape

• carrying capacity

• stored energy

The diagram below represents a process that occurs in human systems. Which process is being shown?

• excretion

• respiration

• circulation

• digestion

An enzyme and four different molecules are shown in the diagram below. The enzyme would most likely affect reactions involving

• molecule A, only

• molecule C, only

• molecules B and D

• molecules A and C

Why does molecule D react best with the enzyme? Hint: think about the "model" we talked about in class!

The diagram below represents a sequence of events that occurs in living things. Letter X represents

• inorganic molecules

• organic molecules

• biological catalysts

• simple sugars

The graph below represents the effect of pH on three different enzymes at normal body temperature. The graph illustrates that enzymes 1, 2, and 3

• are not affected by pH

• work best at different pH levels

• work best in an acidic environment

• work best in a basic environment

The diagram below represents a model of a biological process that occurs in humans at normal body temperature, 37°C. Increasing body temperature to 40°C would interfere most directly with the rate of function of structure

• A

• B

• C

• D
