		glucose and glucose
		glucose and fructose
		maltose and glucose
		starch and glycogen
		deoxyribose and ribose

2. There are different types of microscopes that can be used to provide information about cells. Which type of microscope is used for the observation of living cells?

		scanning electron microscope
		light microscope
		transmission electron microscope

3. To move solutes like amino acids into a cell by active transport, the cell

		maintains a lower concentration of the amino acids in the cytoplasm
		must possess appropriate transport proteins in the plasma membrane
		must move water out of the cytoplasm at the same time
		must have a net gain in energy resulting from active transport

4. What kind of cells make up the basement membrane?

		squamous epithelial cells
		connective tissue cells
		columnar epithelial cells
		cuboidal epithelial cells
		no cells, the basement membrane is an acellular structure, composed of protein

5. Which one of the following is TRUE regarding metabolism?

		An anabolic reaction is one in which a large molecule is broken down into smaller molecules.
		Anabolic reactions generate molecules with decreased energy content.
		Catabolic pathways result in the release of energy.
		Metabolism involves about 200 different chemical reactions occurring in a living organism.
		Linear metabolic pathways occur when the product of one reaction is used as the substrate of the previous reaction.

Answer 1

1. Glucose and Fructose

          The sucrose is a disaccharide made up of glucose and fructose

2. Light microscope

         The light microscope has the ability to observe living cells, by passing a beam of light.

3. Must posses appropriate transport proteins in the plasma membrane.

        The active transport is the transport of substances up their concentration gradient from lower to higher concentration. The specialized protein carrier molecules transports the substances across the membrane.

4. Connective tissue cells

        The basement membrane is a layer, found in four types of epithelial tissue. The cells are closely packed, which is an inert connective tissue.
