BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Enzymes are proteins that act upon substrate molecules and decrease the activation energy necessary for a chemical reaction to occur by stabilizing the transition state.

Detailed explanation-2: -A fundamental task of proteins is to act as enzymes-catalysts that increase the rate of virtually all the chemical reactions within cells. Although RNAs are capable of catalyzing some reactions, most biological reactions are catalyzed by proteins.

Detailed explanation-3: -Enzymes are proteins that help speed up chemical reactions in our bodies. Enzymes are essential for digestion, liver function and much more.

Detailed explanation-4: -Trypsin: These enzymes break proteins down into amino acids in the small intestine. Lactase: Lactase breaks lactose, the sugar in milk, into glucose and galactose. Acetylcholinesterase: These enzymes break down the neurotransmitter acetylcholine in nerves and muscles.
