Question

Cells regulate their activity through
A. Flow of energy
B. Flow of material
C. Flow of information
D. Flow of smoke

Answer 1

Hint:
Before we proceed into the problem, it is important to know the definition of cells.
Cells are the building blocks of life and play a key role in all bodily functions. They carry out various tasks such as reproduction, respiration, growth, maintenance, and defence. Cells also have the ability to change and adapt over time in order to meet new challenges.

Complete step by step answer:
Most cells are made up of proteins and carbohydrates but they also contain lipids which act as cell membranes. These membranes keep cells separate from their surroundings while allowing them to exchange nutrients and gases with the environment.
There are two major types of cells: prokaryotic (single-celled) and eukaryotic (multicellular). Prokaryotes use a single membrane to protect their contents while eukaryotes have multiple membranes that allow them to exchange nutrients and proteins with other cells.
Cells in your body obtain energy from the nutrients you eat, such as glucose (sugar). Cellular respiration transforms glucose and oxygen into water, carbon dioxide, and ATP means adenosine triphosphate, which stands for adenosine triphosphate.
Therefore, the cells regulate their activity through the flow of energy.

Option ‘A’ is correct

Note:
Chemical energy is transformed from one type to another in cells. Potential energy is convertible to kinetic energy. It takes energy to break down (catabolic) or build up (anabolic) molecules. To accept and transfer energy from one chemical step to the next, cells use specialized molecules such as ATP.
