Answer AND Explanation:
A variety of organic and inorganic compounds serve very important roles in living things. The various organic compounds constitute the structures of the body and regulate the chemical processes going on inside it.
Carbohydrates are essential for life since they are oxidised during respiration to release energy. Glucose is the most common respiratory substrate. They are also building blocks of polysaccharides such as starch and cellulose in plants and glycogen in animals.
Lipids are important because they can be oxidized during respiration to release energy. They provide twice the amount of energy for the same weight of carbohydrates. They also act as insulators, source of metabolic water and are major components of cell membranes.
Proteins are important structural components of the cytoplasm and various supportive tissues in the body, transport substances, make up hormones and are used as a source of energy through respiration.
Answer:
The continuity of life from one cell to another has its foundation in the reproduction of cells by way of the cell cycle. The cell cycle is an orderly sequence of events in the life of a cell from the division of a single parent cell to produce two new daughter cells, to the subsequent division of those daughter cells. The mechanisms involved in the cell cycle are highly conserved across eukaryotes. Organisms as diverse as protists, plants, and animals employ similar steps.
Genomic DNA
Before discussing the steps a cell undertakes to replicate, a deeper understanding of the structure and function of a cell’s genetic information is necessary. A cell’s complete complement of DNA is called its genome. In prokaryotes, the genome is composed of a single, double-stranded DNA molecule in the form of a loop or circle. The region in the cell containing this genetic material is called a nucleoid. Some prokaryotes also have smaller loops of DNA called plasmids that are not essential for normal growth.
In eukaryotes, the genome comprises several double-stranded, linear DNA molecules (Figure 6.2) bound with proteins to form complexes called chromosomes. Each species of eukaryote has a characteristic number of chromosomes in the nuclei of its cells. Human body cells (somatic cells) have 46 chromosomes. A somatic cell contains two matched sets of chromosomes, a configuration known as diploid. The letter n is used to represent a single set of chromosomes; therefore a diploid organism is designated 2n. Human cells that contain one set of 23 chromosomes are called gametes, or sex cells; these eggs and sperm are designated n, or haploid.
