Biochemistry is the study of the chemical processes occurring in living matter. It majorly focus on the role, function, and structure of biomolecules. In general it deals with enzymes, carbohydrates, amino acids, proteins, fats, hormones, DNA, RNA, etc.


A vector is a DNA molecule used as a vehicle to artificially carry foreign genetic material into another cell, where it can be replicated or expressed. Cloning vector is a small DNA molecule capable of self-replication inside the host cell. Cloning vector is used for replicating donor DNA fragment within host cell. Vectors can replicate …

Energy coupling reaction.

Exergonic to Endergonic and vice-versa Catabolic to Anabolic and vice-versa Energy coupling: transfer of energy from one reaction to another in order to drive the second reaction. Exergonic reactions: delta G ≤ 0, spontaneous, release free energy Endergonic reactions: delta G ≥ 0, Non-sponatneous, absorbs free energy.   Example: 6th and 7th step of glycolysis
