Which of these factors can affect the initial rate of an enzyme reaction?

• Enzyme concentration

• Substrate concentration

• Temperature

• pH

• All of the above

Some proteins catalyze biochemical reactions. If a genetic defect prevented a protein catalyst from being produced, which of the following do you predict would happen in the cell?

• The cell would find a different type of protein to catalyze the reaction.

• The reaction the protein catalyzes would proceed very slowly or not at all.

• The reaction the protein catalyzes would only occur in some places in the cell.

• The reverse reaction of the one the protein catalyzes would begin to proceed.

Which best explains why the rate of biochemical reaction decreases at high temperatures?

• The activation energy increases

• The shape of the enzyme changes

• The enzyme-substrate complex forms

• The bonds between substrates are broken

What does an enzyme need in order to work properly?

• The right amount of oxygen & CO2

• The right temperature & amount of water

• The right temperature & pH

• The right temperature & pressure

Enzymes are specific. This means that an enzyme only works with molecules that are....

• the right size and shape

• broken down already

• present in water

• too big for the body to handle
