Energy coupling is the transfer of energy from the energy forming step to the biomolecule forming step. The energy forming step is called catabolism wherein the complex molecules are broken down and releasing energy. The energy produced is then used the process called anabolism which produces biomolecules such as proteins.
Afternoon. so yea i think its b too
Answer:
A cell membrane is made of two layers.
The cell membrane is composed by a phospholipid bilayer where the interior side is hydrophobic and non-polar, while the outside is hydrophilic and polar
Pores and proteins in the cell membrane allow passage through it.
The pores and proteins in the cell membrane have several functions such as, for example, cell signaling (proteins) and selective transport (pores)
