Answer:
BMR ; Basal Metabolic Rate
Explanation:
MR is the rate of energy expenditure per unit time by endothermic animals at rest....
Metabolic comprises the process that the body needs to function.
Basal metabolic rate is the amount of energy per unit of timethat a person needs to keep the body functioning at rest
Answer:
protons /H+
thylakoid membrane of the chloroplast
acid.
Explanation:
This is chemiosmosis. And the ultimate aim is to synthesis ATPs. Proton Motive Force generated from the electron transport chain continuously pump protons(H+) from the stroma into the thylakoid membrane of the chloroplast,
The build up of protons/H+ generated electrochemical gradients between this space and the stroma.
Therefore proton/H+ diffused down the gradient into the stroma. The energy generated from the downwards diffusion is used by the ATPase synthase to synthesize ATPs from ADP and inorganic phosphate (Pi), to be used in Calvin Cycle for CHO, productions.
The protons/H+ pumped by PMF and concentrated in the thylakoid memebrane is obtained from the split of Hydrogen atoms to electrons(e-) and H+. since pH is negative Log of [H+], therefore the space will be acidic from large concentration of H+/protons.
Answer:
The correct answer is -
1. right-handed
2. right-handed
3. positive
4. left-handed
5. negative
6. negative
Explanation:
In a circular bacterial chromosome, the structure of DNA is a right-handed double helix In a circular bacterial chromosome.
If DNA is twisted in the right-handed direction, it becomes overwound. Overwinding results in positive supercoiling takes place. If DNA is twisted in the left handd direction, it becomes underwound. Underwinding results in negative supercoiling.
f. One effect negative supercoiling in bacterial chromosomes is to promote separation of the two strands of DNA in the double helix
