Answer:It is this coupling of chemistry and movement that gives proteins the ... to place the protein in a particular location in the cell—an example is the SH2 ... At one level, the cell controls how many molecules of each enzyme it makes ... One of the best understood pump proteins is the calcium transport protein from muscle cells.
Explanation:
Hope this helps.
Answer:
An extracellular molecule activates a membrane protein, which in turn activates molecules inside the cell.
Explanation:
Signal transduction may be defined as the cellular process in which the signal is transmitted into the cells. The signal transduction results in the detection of the stimuli and the effects generated in the body.
The signal transduction initiates the series of cascade for the signal transmission. The protein is activated by the extracellular molecule and activates the different molecules by the phosphorylation at the different steps of the transduction.
Thus, the correct answer is option (c).
Some activities that cell requires energy may include cell division, active transport, protein synthesis etc.
In human, Cells get their energy by the food we eat. The nutrients in the food breaks down into soluble and simple molecules in stomach and small intestine and it is absorbed through the small intestine and assimilated into the cells, becoming part of it, providing the uses for each type of nutrient. And of course, many of them is the energy source.
