Regulation of Enzymatic Activity – Metabolism and Regulation
About the Lecture
The lecture Regulation of Enzymatic Activity – Metabolism and Regulation by Kevin Ahern, PhD is from the course Biochemistry: Basics.
Included Quiz Questions
Which of the following is true regarding control/regulation of enzyme activity?
- Small molecules are essential for allosterism.
- Allosterism involves phosphorylation/dephosphorylation.
- Covalent modification does not involve the cleavage of peptide bonds.
- Sequestration is the primary means of enzymatic regulation.
- DNA splicing is the only way to regulate enzymes.
Which of the following is NOT associated correctly regarding the regulation of enzyme activities?
- Feedback mechanism — controlling a central metabolic pathway by inhibiting the synthesis of the last enzyme of the pathway via end product molecules
- Allosterism — binding of small molecules at specific sites to modulate enzyme activities
- Covalent modifications — maturation of zymogens
- Reversible covalent modifications — addition or removal of the phosphoryl group to control enzymatic activities
- Enzyme synthesis control — controlling the transcription of mRNA of specific gene in response to the cellular surroundings
