As far as I can understand your question, you wish to know why a plant cell consumes ATP to produce glucose when it can directly use the ATP as an energy molecule. ATP is an energy currency and is required in different biochemical pathways. However, it is not a good energy storage molecule. Following are the reasons why production of an energy molecule ...

Endocytosis (specifically you asked about clathrin-mediated endocytosis) is indeed an energy consuming process. the coating of the vesicle may be "spontaneous", but the pinching off of the vesicle, the uncoating of the clathrin, and the transportaion of the vasicle inside the cell all require ATP/GTP hydrolysis. Dynamin - dynamin forms a spiral around the ...

The short answer: no. First, let's get an understanding of the cell cycle control system, as there are some important molecules involved in this system that regulate mitosis. Think of the control system as a series of stoplights: as you mention, there is one stoplight at the G2 phase. There are two additional checkpoints: one at G1 and one in the M (mitotic) ...
