Question

Which is correct for biochemical reactions?
A.These are specific in nature
B.They occur spontaneously.
C.Take place at body temp. \[\left( {\dfrac{{310K}}{{{{37}^\circ }C}}} \right)\] and 1 atm.
D.All of these

Answer 1

Hint: The chemical reactions that take place inside the cells of living things are called Biochemical reactions. Biochemical reactions are specific in nature, it occurs spontaneously, and takes place at body temp. \[\left( {\dfrac{{310K}}{{{{37}^\circ }C}}} \right)\] and 1 atm.

Complete step by step answer:
Biochemical reactions are the reactions that take place inside the biological organisms or can be said that biochemical reaction is the reaction in which one molecule is transformed into another molecule within a cell.
These reactions are specific in nature and they occur spontaneously. It takes place at body temperature i.e. \[\dfrac{{310K}}{{{{37}^\circ }C}}\] and 1 atm. A biochemical reaction is the transformation of one molecule to a different molecule inside a cell of the body so we can say that it takes place at normal human body temperature. The enzymes mediate the biochemical reactions and the enzymes are biological catalysts that help to change the rate and specificity of chemical reactions inside cells. These proteins can specifically catalyse a single reaction so that reactions can be controlled very precisely. This reaction takes place at an active site which is a small part of the enzyme and is usually found in a cleft or pocket lined by amino acids residues, and the rest of the enzyme is used mainly for stabilization.

Therefore, the correct answer is option (D).

Note: The sum of all the biochemical reactions in an organism is called metabolism. It includes both exothermic and endothermic reactions. Water is the key fluid in all living things, i.e. both plants and animals. Biochemical reaction mainly relies on enzymes, which we can say are biological catalysts. Enzymes have evolved to perform optimally in solvent water. Water maintains enzymes, which are proteins, in their active structures through hydrogen bonds (H-bond) and other means.
