Answer:
Skin,muscles and metabolism play a significant role in maintaining his body temperature
Explanation:
Role of skin
In cold environment the blood vessels of the skin constrict to prevent the loss or liberation of heat from his(jim) body.
Role of muscles
The one of principle function of muscle is to store glycogen.The stored glycogen of jim"s muscle undergo glycogenolysis to generate heat inside his body.
Role of metabolism
In cold environment the rate of aerobic respiration and other catabolic reactions such as beta oxidation of fatty acid occur to generate energy in form of heat in his body.
Answer:
The enzyme is<u> b. Catalase</u>
Explanation:
Catalases are ubiquitous biological catalysts or enzymes, that speed up reaction rates. Here, they mediate<u> hydrogen peroxide decomposition</u> into water and oxygen. They are essential in organisms on Earth exposed to oxygen as they protect cells from oxidative damage.
<h2>2 H2O2 -----→ 2 H2O + O2</h2>
hydrogen peroxide water + oxygen
Reactive oxygen species, or free radicals are very reactive- they can cause damage to DNA molecules, RNA and proteins, leading to cell death.
