You should include a few details about how ATP is made in your explanation

Answer 1

1,option-d- fermentation, anaerobic , aerobic

fermentation, only 2 ATP is produced because it goes through glycolysis only.

Anaerobic respirartion- more no.of ATP is produced than fermentation but lesser to aerobic respiration..

Aerobic respiration produces the most number of ATP-36-38ATP

2, a, substrate level phosphorylation

The phosphoryl group from high energy substrate is used for production of ATP in fermentation.

Oxidative level phosphorylation is not possible because oxygen is absent here.

3, b D will inhibit enzyme 3

Feedback inhibition can be called as the process of inhibiting the product formation by the product itself by deactivating the enzyme responsible for the formation of the product.

In the given pathway, the product D can inhibit the enzyme-3 by feedback inhibition,l.

4, b green light is reflected by plant pigments in chloroplast.

The chlorophyll pigment in chloroplast absorbs certain wavelength of colours such as red and blue in the visible spectra and reflects back green light making the plant look green colour.

5, c thylakoid membrane

The ATP synthase is present in the thylakoid membrane. ATP synthase synthesis ATP by using proton gradient
