A virus is a small, infectious agent that is made up of a core of genetic material surrounded by a shell of protein. The genetic material (which is responsible for carrying forward hereditary traits from parent cells to offspring) may be either deoxyribonucleic acid (DNA) or ribonucleic acid (RNA). Viruses are at the borderline between living and nonliving matter. When they infect a host cell, they are able to carry on many life functions, such as metabolism and reproduction. But outside a host cell, they are as inactive as a grain of sand.<span>

Lactic acid fermentation is a biological process by which glucose, fructose, and sucrose are converted into cellular energy and the metabolite lactate. It is an anaerobic fermentation reaction that occurs in some bacteria and animal cells, such as muscle cells. If oxygen is present in the cell, many organisms will bypass fermentation and undergo cellular respiration; however, facultative anaerobic organisms will both ferment and undergo respiration in the presence of oxygen.Lactate dehydrogenase catalyzes the interconversion of pyruvate and lactate with concomitant interconversion of NADH and NAD+.
<span>In homolactic fermentation, one molecule of glucose is ultimately converted to two molecules of lactic acid. Heterolactic fermentation, in contrast, yields carbon dioxide and ethanol in addition to lactic acid, in a process called the phosphoketolase pathway. </span>
Answer;
Lethargy
Explanation;
-The physiologic function that contributes to the increase in intracranial pressure is lethargy.
-Lethargy is an early sign of a changing level of consciousness; it is one of the first signs of increased intracranial pressure. This increased pressure can damage the brain or spinal cord by pressing on important structures and by restricting blood flow into the brain.
<span>Metabolism is the
chemical reactions that take place inside a living organism. The reaction
occurs in the cells. Digestion can be
the best association to metabolism. The metabolic system recognizes which
substances can be nutritious or poisonous. In order to complete this process,
water is needed. The chemicals are
dissolved in water and transported. Without water, no reaction can take place.</span>
Metabolism is considered
as the set of life-sustaining chemical reactions within the living organism’s
body cells.
