question 36

Multiple Choice

The heat given off by living systems can increase the likelihood of a given chemical reaction's taking place. Why is this true?

• A) The enzymes that catalyze reactions in living systems work increasingly better as the temperature decreases.
• B) The heat given off lowers the internal cellular temperature, which allows reactions to proceed more quickly.
• C) The heat allows photosynthesis to occur more rapidly.
• D) The heat speeds molecular movement, increasing the likelihood of collisions between an enzyme and its substrate.
