Identify the labelled parts \(1,2,3,4\) in the Concept of Activation energy shown in the below diagram?
1 1-Activation energy with enzyme, 2-Product, 3-Substrate, 4-Activation energy without enzyme
2 1-Product, 2-Substrate, 3-Activation energy with enzyme, 4-Activation energy without enzyme
3 1-Substrate, 2-Activation energy with enzyme, 3-Product, 4-Activation energy without enzyme
4 1-Activation energy without enzyme, 2Activation energy with enzyme, 3-Substrate, 4 -Product
Explanation:
Exp: B The structure of substrate gets transformed into the structures of products. Activation energy without enzyme is very high, whereas enzyme provides the path of lower activation energy.

The curve given below shows enzymatic activity with relation to three conditions \((\mathrm{pH}\), temperature and substrate concentration)
What do the two axises ( \(x\) and \(y\) ) represent ?
Exp: C Enzymes are generally proteins that act as biological catalysts by accelerating chemical reactions. They generally function in a narrow range of temperature and \(\mathrm{pH}\). Each enzyme shows its highest activity at a particular temperature and \(\mathrm{pH}\) called the optimum temperature and optimum pH. Activity declines both below and above the optimum values. X axis always represents temperature or \(\mathrm{pH}\). \(\quad \mathrm{Y}\) axis represents enzyme activity.

Metabolic processes in living organisms are catalyzed by :
1 hormones
2 enzymes
3 lipids
4 amino acids
Explanation:
Exp: B Metabolic processes in living organism are catalyzed by enzymes. Enzymes are biological catalyst and they catalyze the biochemical reactions. All enzymes are proteins with exception of some small group of catalytic RNA molecules called ribozymes.

\(\quad K_{m}\) is
1 Product
2 Enzyme
3 Constant
4 Unit
Explanation:
Exp: C Michaelis- Menten kinetics is one of the best known and simplest models of enzyme kinetics. \(K_{m}\) act as a Michaelis-Menten constant in the equation- \[ \mathrm{V}_{0}=\frac{\mathrm{V}_{\max }[\mathrm{S}]}{\mathrm{K}_{\mathrm{m}}[\mathrm{S}]} \ where, \(K_{m}\) is called Michaelis constant, \(V_{0}\) is initial velocity, \(\mathrm{V}_{\max }\) is maximum velocity of reaction, and \([\mathrm{S}]\) is substrate concentration.
