Maughan & Gleeson: The Biochemical Basis of Sports Performance
Chapter 02
- Briefly state the role of the following proteins in skeletal muscle:
- myosin
- hexokinase
- lactate dehydrogenase
- carnitine acyl transferase
- troponin
- Distinguish between simple diffusion and facilitated diffusion
across cell membranes and give named examples of each that are found in
the sarcolemma of muscle.
- Identify the following compounds as carbohydrates, lipids,
proteins, amino acids or purines: insulin, alanine, palmitic acid,
glutamic acid, glucose, adenine, glucagon, guanine, cholesterol,
glycogen.
- What factors affect enzyme activity?
- List the biochemical characteristics that distinguish between Type I and Type II muscle fibres.
- Briefly state the role of the following intracellular structures in skeletal muscle:
- mitochondrion
- lysosome
- sarcoplasmic reticulum
- rough endoplasmic reticulum
- myofibril
What determines the primary, secondary and tertiary structure of proteins?
Give four named examples that illustrate the diversity of protein function.
- Explain how enzyme activity can be altered by allosteric and covalent modification.
- Explain why eccentric muscle actions cause muscle weakness and delayed onset muscle soreness.
- What factors determine the maximal isometric force that can be generated by a muscle group?
