Answer:
proteins
Explanation:
Transport protein is responsible for the movement of molecules across the cell membrane. This process occurs in active transport. Active transport is a type of transport in which energy is used in the form of Adenine tri phosphate (ATP) to move particle across semi-permeable of the cell. Molecules such as nutrients, Sodium, glucose, oxygen and carbondioxide can pass through it.
Because things take time to grow
Gap 2 (G2): During the gap between DNA synthesis and mitosis, the cell will continue to grow and produce new proteins. ... Mitosis or M Phase: Cell growth and protein production stop at this stage in the cell cycle. All of the cell's energy is focused on the complex and orderly division into two similar daughter cells.
