What cellular process(es) is/are responsible for the increase in protein content associated with the gap phases of the cell cycle?

Protein/enzyme synthesis

Explanation:

The process of synthesis of protein in the cell is mainly responsible for the increase in the protein content of the cell.

The process which is also known as the translation process of gene expression takes place at the G1 and G2 phases of the interphase of the cell cycle.

During protein synthesis, mRNA synthesized in the nucleus are transported to the cytoplasm and the genetic codes on the mRNA are translated into their respective amino acids linked together by polypeptide bonds. The protein are then folded in specific ways for specific enzymes.

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
