The reaction of a particular endothermic reaction whether in a negative or positive entropy change is always spontaneous. Temperature differences will be spontaneous throughout the reaction but one thing is constant, heat will always be produced within the said reaction.
The eukaryotic organisms have the process of mitosis but differently than the process of the prokaryotic because the prokaryotic organisms dont have the dna enclosed in a nucleus. Mitosis needs to occur in eukaryotic organims because the cell could keep growing an it is going to be less efficient in moving material across the cell membrane. They reason why mitosis happens is because volume and surface are do not increase at the same rate.
Explanation:
Answer:
Pumps, also called transporters, are transmembrane proteins that actively move ions and/or solutes against a concentration or electrochemical gradient across biological membranes. One moves with the concentration gradient (high to low) which powers the movement of the other against the gradient (low to high).
Answer:
Some of these proteins serve to transport materials into or out of the cell. Carbohydrates are attached to some of the proteins and lipids on the outward-facing surface of the membrane. These form complexes that function to identify the cell to other cells.
