What molecules are the main electron carriers of the krebs cycle? a) nadh and fad b) nadh and fadh2 c) nad+ and fad d) nad+ and fadh2

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.

relative humidity, temperature and dew point -- are bound together in the mathematical relationship below. relative humidity changes when temperatures change. because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air. so i would say a
