Question

check all that apply
catalytic activity
storage of genetic information
storage of energy
membrane structure
signaling molecules (such as hormones or neurotransmitters)

Explanation:

Proteins can have catalytic activity (e.g., enzymes are proteins that catalyze biochemical reactions). Nucleic acids store genetic information, not proteins. Lipids are mainly for energy - storage. Proteins are important components of membrane structure. Some proteins can act as signaling molecules like some hormones and neurotransmitters.

Answer:

catalytic activity, membrane structure, signaling molecules (such as hormones or neurotransmitters)
