LECTION A: BASIC AGRICULTURAL CHEMISTRY 1. Give ONE word/term for each of the following descriptions. Write only the word/term next to the question number (1.1.1 to 1.1 .5 ) in the ANSWER BOOK. 1.1.1 Amino acids which can be synthesized by the body. 1.1.2 Group made up of a carbon atom joined to an oxygen by a double bond. 1.1.3 Accepts \( H^{+} \)ions. 1.1.4 Disaccharide formed from glucose and galactose molecule. 1.1.5 Diagram which consists of atomic orbital, protons, electrons, nucleus and neutrons.

1.1.1 Nonessential   *Amino acids synthesized by the body are known as nonessential amino acids.* 1.1.2 Carbonyl   *A group consisting of a carbon atom double-bonded to an oxygen atom is called a carbonyl group.* 1.1.3 Base   *A substance that accepts \(H^{+}\) ions is defined as a base.* 1.1.4 Lactose   *A disaccharide formed from a glucose and a galactose molecule is known as lactose.* 1.1.5 Atom   *A diagram showing atomic orbitals, protons, electrons, nucleus, and neutrons represents an atom.*
