Question

multiple select question
select all that apply
proteins have many functions, including
energy storage.
motion.
defense.
support.
transport.

Explanation:

To determine the correct functions of proteins:

• Energy storage: Some proteins (like albumin) can store energy, so this is correct.
• Motion: Proteins like actin and myosin are involved in muscle contraction for motion, so this should be selected (wasn't initially).
• Defense: Antibodies (proteins) defend against pathogens, so this is correct.
• Support: Structural proteins like collagen provide support, so this is correct.
• Transport: Proteins like hemoglobin transport substances, so this should be selected (wasn't initially).

The initially selected "energy storage", "defense", "support" are correct, and "motion" and "transport" should also be selected as proteins have these functions.

Answer:

The correct options (after correction) are:

• energy storage.
• motion.
• defense.
• support.
• transport.

(Note: The initial selection missed "motion" and "transport" which are also functions of proteins. Motion is enabled by contractile proteins, transport by carrier/channel proteins.)
