What role do proteins play?

Answer 1

Proteins have a wide variety of jobs. Some proteins are used in the maintenance of the cells structure. Proteins can be used to move various portions of the cell do different locations within the cell (eg chromosome movement during mitosis). Other proteins, found in cell membranes are used in the active and passive transport of molecules (eg. aquaporins, sodium channels). Many proteins are enzyme which catalyze reactions within the cell (eg. Hexokinase).

In short proteins (in general) do not have one specific job but different proteins have different functions.

Answer 2

Proteins have many functions. They are used as enzymes to enable reactions to happen like the synthesis of sugars. Proteins provide structure to cells as well as contribute to cell motility. They are used for cell signaling, transport, and defense.

Answer 3

The job performed by proteins can be understood when we look into how they are classified. There are two major classes of proteins: Structural proteins - provide strength and rigidity to regions in the body like hair and nails Globular proteins - act as enzymes and hormones that are essential for all metabolic processes

Answer 4
