Term Definition

3. Carbohydrate
a. Molecule that's a source of energy in the body

4. Nucleic acid
b. Many structures and enzymes in the body are made of these

5. Lipids
c. One substance that makes up cell membranes

6. Proteins
d. The molecule that carries the genetic material in the cell

Answer:

1. In an ionic bond, the electrons are lost or gained between atoms. In a covalent bond, the electrons are shared between atoms.

2. Protons and electrons both have an electric charge. Protons have a positive charge and electrons have a negative charge. This means that their charges are equal and opposite. The nature of the charge influences how electricity moves through an atom.

3. a

4. d

5. c

6. b

Explanation:

The ionic bonds are formed between the metal and nonmetal with the opposite charges, whereas the covalent are between the nonmetals. The electricity is influenced both by the electron (negative) and protons (positive) of the atom.

What is an atom?

An atom is made of subatomic particles with different charges. The electron is negative and protons are positive charge particles that affect the movement of the electric current as their charges influence the electric charge.

The matches for the macromolecules with their definitions are given as,

  • Carbohydrates are the macromolecules involved in the storage of energy. Hence, option a is correct.

  • Nucleic acids are molecules consisting of DNA and RNA that act as genetic and heritable material. Hence, option d is correct.

  • Lipids are involved in the structural composition of the cell membrane and store energy. Hence, option c is correct.

  • Proteins make various enzymes and structures in the body that plays the most crucial role. Hence, option b is correct.
