Question

which of the following are functions of carbohydrates? (select all that apply) check all that apply catalytic activity storage of genetic information storage of energy structural support signaling molecules (such as hormones or neurotransmitters)

Explanation:

Carbohydrates can act as signaling molecules (e.g., glycoproteins in cell - cell recognition), provide structural support (e.g., cellulose in plant cell walls), and store energy (e.g., starch in plants and glycogen in animals). They do not store genetic information (that's the role of nucleic acids) and generally do not have catalytic activity (enzymes, mostly proteins and some RNAs, have catalytic activity).

Answer:

• Signaling molecules (such as hormones or recognition elements)
• Structural support
• Storage of energy
