Answer:
C. only glycolysis and the Krebs cycle
Explanation:
Conversion of 1,3-bisphosphoglycerate into 3-phosphoglycerate and conversion of phosphoenolpyruvate into pyruvate during glycolysis obtains a total of 4 ATP molecules per glucose (2 from each reaction). Here, ATP formation occurs by the transfer of the phosphoryl group from a substrate such as 1,3-bisphosphoglycerate. Therefore, it is called a substrate-level phosphorylation.
Similarly, oxidative decarboxylation of alpha-ketoglutarate into succinyl CoA and conversion of succinyl CoA into succinate forms 2 ATP molecules per glucose during Kreb's cycle. Here, the energy for ATP synthesis is provided by oxidative decarboxylation of a substrate. Therefore, it is also substrate-level phosphorylation.
Answer:
An association between two organisms in which one benefits and the other derives neither benefit nor harm.
Explanation:
The answer is A, and this is true because trauma can not be transmitted or caught by humans or animals but a virus , faulty nutrition & congenital defects can. hope this helps :)
