Cells link monomers together to form polymers by a dehydration reaction, a reaction that remove a molecule of water as two molecules become bonded together.-Each monomer contribute part of the water molecule that's released during the reaction. So we know that the cells of the body are made up of molecules. In this article, we explain some of the structures found in cells and describe a few of the many types of cell … Cells are made of proteins, which are a type of molecule, and water, which is another molecule, and other things which are all made of molecules. Humans are made up of trillions of cells — the basic unit of life on earth. Like all viruses, coronaviruses can only grow inside host cells; they rely on the host cell's molecules to multiply. Within the centre of the cell is DNA and RNA, both extremely complicated molecules. Nucleic acids are long chains made from many smaller molecules called nucleotides. Blood cells are carried around the body in the plasma. Water also acts as a transport medium in plants. Virus is studied under biology because it has genes, and it evolves. Within cells, the cytoplasm is made up of a jelly-like fluid (called the cytosol) and other structures that surround the nucleus. Layla Carrington General Bio 1 Dr. Amy Hofmann February 11, 2020 The Molecules of Cells The Molecules of Life All living things are made up of 4 classes of large biological molecules Carbohydrates, Lipids, Proteins, Nucleic Acids Biological Molecules are Organic Organic: molecules that consist of atoms of carbon and 1 or more other elements, held together by … Virus is not a cellular organism, it is only a living particle. Blood is made up of cells and a liquid called plasma. Plasma is 92% water and acts as a transport medium for many dissolved substances. RNA is a lesser-known molecule but it also plays an important role in cells. For example, is a compound as it contains one calcium molecule and two chlorine molecules. Whereas sharing or transfer of electrons take place between the molecules of a compound. Cytoskeleton The cytoskeleton is a network of long fibers that make up the cell’s structural framework. Without RNA, the information in DNA would be useless. Molecules are made of cells and cells are made of tissues. Hence, we can conclude that compounds are made up of molecules. Outside the host cell, a virus shows no sign of life. Cells are made of proteins, which are a type of molecule, and water, which is another molecule, and other things which are all made of molecules. d. Atoms make up organs and … So we know that the cells of the body are made up of molecules. Thus all viruses are obligatory parasite, they replicate inside cells. In animals, water helps to break down and digest food molecules. c. Cells make up tissues and tissues make-up organs. It is made of molecules, some acting as internal and external messengers, some forming the outer membrane, some carrying out the burning of fuel chemicals, and much more. RNA molecules are used to translate the information stored in DNA molecules and use the information to help build proteins. Cells are made of molecules,molecules are made of atoms,atoms are made of energy.so Thread starter jimmy1200 ... muscle, cells, etc..., not completely true?
