Question

Cells can do three kinds of work: making proteins and polymers, transporting substances, and

A)

PΔV work to move a piston.

B)

energy work.

C)

mechanical work, such as contracting muscles.

D)

heat work.

Answer 1

The correct answer is - option C. mechanical work, such as contracting muscles.

Step-by-step explanation:

Cells perform three major work that can be categorized in chemical work, mechanical work, and transport work. Production of the large molecules is an example of chemical work.

The transport work includes transporting substances across the membrane such as moving the ions across a plasma membrane. Contraction of the muscles and the movements of cilia is mechanical work.
