Consider the following statementsAssertion (A): An enzyme is basically...
Assertion (A): An enzyme is basically a protein which acts like a catalyst in the metabolic reactions of an organism.

Reason (R): The pancreatic juice is basically composed of three enzymes trypsin, amylase, and lipase.

To understand the given statements, let's break them down and evaluate their accuracy.

A. Enzymes as Catalysts
Enzymes are biological molecules, typically proteins, that act as catalysts in metabolic reactions. They facilitate chemical reactions by lowering the activation energy required for the reaction to occur. This enables the reactions to proceed at a faster rate and under physiological conditions. Enzymes do not alter the equilibrium of a reaction; instead, they accelerate the rate of the reaction by providing an alternative pathway with lower energy requirements. Hence, Assertion (A) is correct.

R. Pancreatic Juice Composition
The pancreatic juice is a clear, alkaline secretion produced by the pancreas. It plays a crucial role in the digestion and absorption of nutrients in the small intestine. The pancreatic juice is composed of various enzymes, including trypsin, amylase, and lipase.

1. Trypsin: Trypsin is an enzyme that breaks down proteins into smaller peptides. It is secreted as an inactive precursor called trypsinogen, which is activated by another enzyme called enterokinase in the small intestine.

2. Amylase: Amylase is an enzyme that catalyzes the breakdown of complex carbohydrates, such as starch and glycogen, into simpler sugars like glucose and maltose.

3. Lipase: Lipase is an enzyme that breaks down fats or lipids into fatty acids and glycerol. It is essential for the digestion and absorption of dietary fats.

Hence, Reason (R) is also correct.

Explanation of the Relationship between A and R
Both the Assertion (A) and Reason (R) are true, but the Reason does not provide a correct explanation for the Assertion.

The Assertion states a general fact about enzymes, emphasizing their role as catalysts in metabolic reactions. On the other hand, the Reason specifically mentions the composition of pancreatic juice, which includes trypsin, amylase, and lipase. While these enzymes are indeed proteins that act as catalysts in the metabolic reactions of an organism, the Reason does not explain why enzymes, in general, function as catalysts.

Therefore, the correct answer is option (B) - Both A and R are true, but R is not the correct explanation of A.

It has long been known that the rate of oxidative metabolism (the process that uses oxygen to convert food into energy) in any animal has a profound effect on its living patterns. The high metabolic rate of small animals, for example, gives them sustained power and activity per unit of weight, but at the cost of requiring constant consumption of food and water. Very large animals, with their relatively low metabolic rates, can survive well on a sporadic food supply, but can generate little metabolic energy per gram of body weight. If only oxidative metabolic rate is considered, therefore, onemight assume that smaller, more active, animals could prey on larger ones, at least if they attacked in groups. Perhaps they could if it were not for anaerobic glycolysis, the great equalizer. Anaerobic glycolysis is a process in which energy is produced, without oxygen, through the breakdown of muscle glycogen into lactic acid and adenosine triphosphate (ATP), the energy provider. The amount of energy that can be produced anaerobically is a function of the amount of glycogen present—in all vertebrates about 0.5 percent of their muscle’s weight. Thus, the anaerobic energy reserves of a vertebrate are proportional to the size of the animal. If, for example, some predators had attacked a 100-ton dinosaur, normally torpid, the dinosaur would have been able to generate almost instantaneously, via anaerobic glycolysis, the energy of 3,000 humans at maximum oxidative metabolic energy production. This explains how many large species have managed to compete with their more active neighbours: the compensation for a low oxidative metabolic rate is glycolysis.Q. According to the author, glycogen is crucial to the process of anaerobic glycolysis because glycogen
