- All coenzymes are cofactors, but not all cofactors are coenzymes. Explain this statement briefly.arrow_forwardThe lipid shown here is produced by certain microorganisms that live in extremely warm environments, such as hot springs. Assuming that this lipid makes up a portion of the organism’s membrane lipids, would the organisms produce more of this lipid or less of this lipid as the temperature increased from 45°C to 65°C?arrow_forwardThere are microorganisms that live in extreme environments like volcanic vents which temperature reaches to 80 degrees celsius. Considering enzymes experience denaturation at higher temperatures, how do the enzymes of these microorganisms remain active at such extreme condition?arrow_forward
