Chapter 3, Problem 11TY
Summary Introduction
Introduction:
Some types of cellular activities require an input of energy, while some do not. The processes that do not require the input of energy are usually aided by physical processes such as diffusion. The cellular activities, which require energy, usually utilize energy by breaking down a high energy molecule called ATP (adenosine triphosphate).
