The graph shows the effect of temperature on the rate of carbon dioxide (CO2) production in place of cells as a result of cellular respiration.

Question

Based on the graph, select from the dorp=down menus to correctly complete the statements.

When temperature increases, the rate at which glucose is used by cells is expected to 1.____

When temperature decreases, the rate of ATP production by cells is expected to 2.___

1:
a. decrease
b. increase
c. stay the same

2.
a. decrease
b. increase
c. stay the same

Answer 1

Based on the effect of temperature on the rate of cellular respiration, the correct completions for the statements are:

1. b. increase
   When temperature increases, the rate at which glucose is used by cells is expected to increase, as higher temperatures typically enhance enzymatic activity involved in cellular respiration.

2. a. decrease
   When temperature decreases, the rate of ATP production by cells is expected to decrease, as lower temperatures can slow down the enzymatic reactions necessary for producing ATP.

So, the completed statements are:

1: b (increase)
2: a (decrease)
