Because the number of electrons does not equal the number of protons, each ion has a net charge. Organic and inorganic compounds must be consumed by living organisms in order for them to be broken down for energy and used as building blocks for the components of life. The study of the structure and function of these biomolecules, as well as their role in biological processes at the molecular, cellular, and organismal levels, is known as the Chemistry of Life. Each element is made of atoms, each with a constant number of protons and unique properties. D. Chemical reactions release or absorb energy 1. DNA is the genetic material found in all living organisms, ranging from single-celled bacteria to multicellular mammals. Each protein has its own unique sequence and shape held together by chemical interactions. More bonds are broken than are formed. HelpWork: Chapter 2: The Chemistry of Life. A catalysts lowers activation energy 1. The electron from the hydrogen atom divides its time between the outer shell of the hydrogen atom and the incomplete outer shell of the oxygen atom. Plants are able to synthesize glucose, and the excess glucose is stored as starch in different plant parts, including roots and seeds. As stated earlier, each element has its own unique properties. Lithium has only one electron in its outermost shell, beryllium has two electrons, boron has three, and so on, until the entire shell is filled with eight electrons, as is the case with neon.
The second and third energy levels can hold up to eight electrons. Although glucose, galactose, and fructose all have the same chemical formula (C6H12O6), they differ structurally and chemically (and are known as isomers) because of differing arrangements of atoms in the carbon chain (Figure 3. This interaction is called a hydrogen bond. Orange juice is mildly acidic (pH = approximately 3. Chapter 2 the chemistry of life answer key. D. Fats and oils have different types of fatty acids 1).
