(1) reproductive hormones
(2) carbohydrates
(3) antibodies
(4) biological catalysts
Answer and Explanation:
All of the answer choices are molecules in our body. Let's look at the definition of each choice one at a time. Reproductive hormones such as testosterone and estrogen function to regulate reproductive functions such as menstrual cycle, sperm production etc.
Carbohydrates are molecules from which our bodies derive energy in the form of ATP.
