Cells need to bring in molecules to carry out cellular processes. True or False

Answer: True

Explanation:

For cells to carry out cellular processes, cell needs to bring in molecules from the surrounding environment.

Cellular nutrients that are transported across the cell membrane include water, oxygen, carbon dioxide, sugars, fats, ions among many others, for cellular metabolism to occur.

The permeability of substances across the cell membrane is dependent on their solubility in lipids. Water soluble compounds are generally impermeable and require carrier mediated transport.

Process in which cell bring in molecules include

1. Passive transport which doesn't require energy

2. Active transport which requires energy

3. Pumps which can drive molecules against the concentration gradient using energy
