Cellular processes are carried out by many different types of molecules, mostly proteins. The function of each protein molecule
Vitek1552 [10]

Answer:

option A

Explanation:

The protein specific sequence also known as the primary sequence is determined by the sequence of its amino acids linked together by peptide bonds. The sequences of amino acids determine the proteins that will eventually be synthesized. This proteins becomes functional when correct folding pattern/ native conformation of the protein occurs which determines the shape of the proteins. peptide bonds hold the amino acid sequences together, hydrogen bonds involving components of the peptide bonds allow for the existence of the secondary structure either the alpha helix or the beta pleated sheets and then disulphide bonds and other type of bonds helps in the folding of the protein to become a functional protein.

11. How does active transport differ from all other forms of transportation?
Nastasia [14]

Though both active transport and passive transport involve ion movement and use ion channels to move ions across the cell membrane, in or out of the cell.

Passive Transport (or Diffusion) moves ions from high concentration to low, using no metabolic energy. Active Transport moves ions from low concentration to high, using metabolic energy in the form of ATP.

So the answer is C.
