Other molecules such as proteins, starch and sugar are simply too large to diffuse across the membrane. Sometimes, some of these large molecules are transported across the cell membranes by carrier proteins; this does not require energy and as a result is a form of passive transpor
Answer:
The correct option is b. G1 phase. When a newly formed cell enters into interphase and begins conducting metabolic functions, it is in <u>G1 phase.</u>
Explanation:
The cell cycle comprises a whole series of events or phases that take place in the cell during its growth and division. A cell spends most of its time at the stage called<em> the interface</em>, and during this time it grows, duplicates its chromosomes and prepares for cell division. The cell cycle has different phases, which are called G1, S, G2 and M.
G1 phase is that in which the cell prepares to divide, during this phase, the cell grows rapidly, while performing routine metabolic processes. It also produces proteins necessary for DNA replication and copies some of its organelles in preparation for cell division. A cell normally spends most of its life in this phase. This phase is also known as Gap 1 phase and actively synthesize RNA and proteins.
G0 phase is a period or cycle of a cell where it remains in a resting state, in this phase mature cells that leave the cell cycle are placed.
G2 phase, during this stage, the cell makes the final preparations for its division.
the minimum quantity of energy that the reacting species must possess in order to undergo a specified reaction.
