Question

metabolism can be divided into catabolic and anabolic reactions. how are these connected? you can always check the theory tab on your labpad if you would like to read up on the theory before answering.
a) catabolic reactions produce energy and anabolic reactions process waste
b) there is no connection between either type of reaction
c) anabolic reactions generate energy that catabolic reactions use
d) catabolic reactions generate energy that anabolic reactions use

Explanation:

Catabolic reactions break down molecules to release energy, while anabolic reactions build complex molecules and require energy. The energy produced by catabolic reactions fuels anabolic reactions. Option a is incorrect because anabolic reactions do not process waste; option b is wrong as the two are tightly linked; option c reverses the energy flow direction.

Answer:

d) Catabolic reactions generate energy that anabolic reactions use
