Question

All of the following are principle roles of proteins within cells EXCEPT:

	a.	Energy storage
	b.	Structure
	c.	Transport
	d.	Catalysis

there is only one correct answer

Answer 1

a) Energy storage

Proteins perform a wide variety of functions. The roles of proteins include serving as structural components of cells and tissues, acting in the transport and storage of small molecules (e.g., the transport of oxygen by hemoglobin), transmitting information between cells (e.g., protein hormones), and providing a defense against infection (e.g., antibodies). The most fundamental property of proteins, however, is their ability to act as enzymes.
