Answer:
The phenomenon of generating cellular energy in the presence of oxygen is termed as aerobic respiration. In the process of aerobic respiration, the generation of 36 ATPs takes place. The initial step of aerobic respiration is glycolysis, which is followed by the citric acid cycle and electron transport chain.
On the other hand, the phenomenon of generating energy in the absence of oxygen is termed as anaerobic respiration. It is a comparatively faster process in comparison to aerobic respiration in which the generation of two ATPs takes place. The phenomenon of anaerobic respiration takes place within the cytoplasm, where energy is discharged from glucose by the process of glycolysis, and the recycling of NADH takes place back to NAD+ by the process of fermentation.
Thus, it can be seen that the process of glycolysis takes place both in aerobic and anaerobic conditions.
D - initiation - elongation - termination
Because people back then did not have enough access to technology like we do today
Answer:
the immune system needs B cells and memory B cells form into memory cells so that remember the same pathogen and the antibody used to take it down for faster antibody production in future infections when most of the same antigens infect the body again.
Explanation:
When the body senses foreign substances like antigens, the immune system works to recognize the antigens and get rid of them. B Cells that have a certain antibody codes/proteins for the specific antigen are triggered or activated by T cells to make the specific antibodies, or immunoglobulins, to use against the antigens, by locking onto the antigen and putting the antibodies into the antigen directly.
