All organisms perform whether or not oxygen is present. a). glycolysis b). aerobic respiration c). photosynthesis d). none of the above

Glycolysis

Explanation:

Glycolysis is an universal process which takes place in all the organism from bacteria to humans. It can occur whether oxygen is present or not. It is the first step of cellular respiration that takes place in cytosol.

During glycolysis, breakdown of the glucose into pyruvate occurs with the formation of two energy molecules of ATP and two NADH molecules.

Thus, the correct answer is option (A).

g1

choices:

a. g2. b. g1. c. m

cell division has two checkpoints namely, g1

checkpoint and spindle assembly checkpoint. the checkpoint which determines if

division has properly occurred is the g1 checkpoint. at this point, is a damage

in the dna is detected or  the has not reach the optimum size, the cell is

stopped in g1 and is not allowed to proceed to further process.
