Which of the following does the enzyme carbonic anhydrase most likely do to a metabolic reaction?

• The enzyme increases the rate of the reaction.

• The enzyme reverses the direction of the reaction.

• The enzyme releases carbon molecules to be used later.

• The enzyme releases oxygen atoms to balance the reaction

In the leaf cells of a plant, enzymes control the rate at which carbon dioxide is converted into glucose. Which environmental factor would most affect the action of the enzyme?

• wind

• rainfall

• air pressure

• temperature

In the human mouth, saliva contains several enzymes used in digestion, one of which is amylase. When a person chews on a saltine cracker for a short while, a sweet taste is detected. What reaction is taking place in response to the enzyme amylase?

• Amylase is specifically binding with salt to create glucose.

• Amylase is producing the starch necessary to produce glucose.

• Amylase is increasing the activation energy needed to produce glucose.

• Amylase is catalyzing the digestion of the saltine cracker to produce glucose.

• the Y chromosome is shorter than the X chromosome

• there are 3 chromosomes at the 21st chromosome as a result of nondisjunction

• there is only one X and one Y chromosome
