B. Reactions that involve enzymes require more energy than reactions without enzymes.
C. The enzyme lactase will slow down the breakdown of lactose in the small intestines.
D. Lactase will require more energy to break down lactose, and less energy is required if it is not present.
Answer:
A. The enzyme lactase will speed up the breakdown of lactose in the small intestines.
Explanation:
A. The enzyme lactase will speed up the breakdown of lactose in the small intestines. - this is true. Lactase is an enzyme that catalyses the breakdown of lactose. This means it greatly reduces the activation energy required for the breakdown of lactose, and the reaction will happen quicker.
B. Reactions that involve enzymes require more energy than reactions without enzymes. This is false. Reactions that involve enzymes require less energy that reactions without
C. The enzyme lactase will slow down the breakdown of lactose in the small intestines. This is false. It will speed it up
D. Lactase will require more energy to break down lactose, and less energy is required if it is not present. This is false, more energy is required if it is not present
