The ratio of the enzyme to substrate molecule can be as high as

Assertion (A) In presence of enzyme, substrate molecule can be attacked by the reagent effectively. Reason (R) Active sites of enzymes hold the substrate molecule in a suitable position.

Assertion (A) In presence of enzyme, substrate molecule can be attacked by the reagent effectively. Reason (R) Active sites of enzymes hold the substrate molecule in a suitable position.

Assertion : Enzymes have active sites and substrates reactive sites, on their surfaces respectively. Reason : Active and reactive sites push the enzyme and substrate molecules away from each other.

Assertion : Enzymes lower the activation energy. Reason : A substrate molecule can be acted upon by a particular enzyme.
