Responda
- True
- False
Questão 12
Questão
Which of the following statements about functions of lipids are CORRECT?
Responda
-
Lipids provide structure.
-
Lipids like testosterone perform regulatory functions.
-
Lipids store energy.
-
Lipids help resist tension.
Questão 13
Questão
Which statement BEST describes the differences between DNA and RNA?
Responda
-
DNA is a double helix while RNA is a single strand.
-
DNA is made up of four bases, and RNA shares three of these, while having one unique base (uracil in place of thymine).
-
DNA is a double helix with hydrogen groups, and contains the bases thymine, adenine, guanine, and cytosine. RNA is a single strand with -OH groups, and uses uracil in place of thymine.

One gene can code for several proteins
-
Proteins are mainly for structural support.
Questão 15
Questão
Which of these are functions of proteins?
Responda
-
Proteins provide structure e.g collagen to resist tension.
-
Proteins are regulatory and maintain homeostasis e.g. insulin in the plasma membrane.
-
Proteins are contractile e.g. actin and myosin in muscle fibers.
-
Proteins can transport things e.g. haemoglobin moving oxygen via the cardiovascular system.
-
Proteins can store materials e.g egg white - albumin
-
Some proteins are highly acidic and act to break down cells in their regulated death cycle.
-
Some proteins are immune proteins which protect the system e.g. antibodies like IgG
