171 Portage Learning questions
and answers
Microbiology is the study of what? - ANSWER-My ANSWER: Microbiology is the
study of microorganisms and their biological processes at what is called the
"micro" or "microscopic" level.
ANSWER Key: Microbiology is the study of microbes (microorganisms and viruses)
and their biological processes.
What is the smallest biological unit of life? - ANSWER-the cell
What is a macromolecule? - ANSWER-My ANSWER: Macromolecules are large and
complicated molecules that are made up of smaller molecules. Examples of
macromolecules are polysaccharides, lipids, nucleic acids, and proteins.
More info:
- Proteins are made up of amino acids (of which there are 20 different types).
- Nucleic Acids can be either DNA or RNA. Nucleic acids are made up of
nucleotides. For DNA, the nucleotides are adenine (A), guanine (G), cytosine (C)
, and thymine (T). For RNA, the nucleotides are adenine (A), guanine (G), cytosine
(C) and uracil (U).
- Lipids are made up of hydrocarbons.
- Polysaccharides are made up of monosaccharides.
ANSWER Key: A macromolecule is classified as a complex molecule that is
composed from smaller subunits.
What are the four main types of macromolecules? - ANSWER-My ANSWER:
polysaccharides, lipids, nucleic acids, proteins
ANSWER Key: Proteins, nucleic acids, lipids and polysaccharides
What various functions do proteins have in a cell? - ANSWER-My ANSWER:
Proteins have several functions in the cell;
1. To assist materials in moving in and out of the cell
2. To act as a catalyst enzyme which speeds up a biochemical process
3. To provide structure in the cell
4. To enable movement (e.g. filaments)
ANSWER Key: Proteins may facilitate the movement of materials in or out of a cell.
Some can act as enzymes that catalyze, or speed up, biochemical processes.
Others play a structural role while other proteins, such as filaments, enable
movement.
