Which of these processes does not require the cell to use energy A cell division b protein synthesis c DNA replication D diffusi
weeeeeb [17]

Answer:

D diffusion across a membrane

Explanation:

Based on whether or not energy input is required, there are two types of processes viz: passive and active. Passive processes are those that do not require energy input in form of ATP while active processes require energy input to occur.

An example of passive process is DIFFUSION, which is the movement of molecules from a region of high concentration to a region of low concentration across a membrane. Diffusion is passive i.e does not require energy, because movement occurs down a concentration gradient.

Other processes in the options like cell division, DNA replication and protein synthesis all require energy input to occur.

What is the role of phospholipids and proteins in controlling the passage of substances across the cell surface membrane, making
Anastaziya [24]
Phospholipids are the substance/structure that is the building block of the cell membrane. Without phospholipids, we wouldn't even have a cell membrane and wouldn't really have any way how to shield and guard or control th epassage of substances across the cell surface. The cell membrane is at the same time partially permeable; this means it will let certain ions that can be found in the intra and extracellular fluid in and out, while others will be kept from moving so freely.
