Question

give an example for each of the four basic substances of a cell (carbogydrates, proteins, lipids, and nucleic acids)

Answer 1

Carbohydrates are the sugars, starches and fibers found in fruits, grains, vegetables and milk products

proteins are meats.

Lipids are a group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E, and K), monoglycerides, diglycerides, triglycerides, phospholipids, and others.

nucleic acids are complex organic substance present in living cells, especially DNA or RNA, whose molecules consist of many nucleotides linked in a long chain.

Answer 2

Answer:

Carbohydrates can be defined as the sugars, starch and fibers found in the fruits, grains, milk products and vegetables.

They are the most form form of energy found in nature. It is a source of instant energy.

Proteins can be defined as the polymer which is composed of amino acids. It is organic compound made of carbon, hydrogen and oxygen, nitrogen and sulfur.

It is found in the non vegetarian diet, meat, chicken, egg. Pulses and soya bean are also some sources of protein.

Nucleic acids are the polymer of nucleotide which contains sugar, nitrogenous bases and phosphate bond. It is the genetic material found in all the living organisms. Example: DNA and RNA.

Lipids commonly known as fat. These compounds are found in the form of fat inside the body of an organism. Example: oil, waxes and vitamin A, D, E,K.
