The right answer is B) NADH and FADH2.
NADH, FADH2 are molecules involved in the Krebs cycle, they carry electrons and H + protons.
NAD is involved in metabolism as an electron carrier in oxidation-reduction reactions, NAD + as an oxidant and NADH as a reducing agent.
Flavin adenine dinucleotide (FAD) is an oxidation-reduction cofactor derived from riboflavin (vitamin B2). It is associated with the enzymes of the class of oxido-reductases to which it is linked by a covalent bond: it is a prosthetic group.
The redox couple is: FAD ==> FADH.
Answer:
The correct option is a (true).
Explanation:
Personally i have experienced that microbes living in saline condition were isolated from soil and grown them on Lauria Bertani media.
Plants converts solar energy into chemical energy through the process of photosynthesis . The electron and proton from the water molecules are used to produce energy transport molecules i.e ATP and NADPH, in the light reaction phase of photosynthesis. The energy of the sun excites the chlorophyll molecule which in turn release high energy electron. The energy of ATP and NADPH is further used to fix the carbon in the Kelvin cycle.
