Compare the structures of myoglobin and haemoglobin, and explain
how each structure relates to the function of the protein. (NO
DIAGRAMS or pictures in writing )
Which of the following statements are correct regarding the
structures of myoglobin and haemoglobin and their abilities to bind
oxygen?
Select one or more:
a. When haemoglobin has two oxygen molecules bound, it
effectively has a lower affinity for oxygen than when it has no
oxygen molecules bound.
b. Myoglobin and haemoglobin have very similar tertiary
structures.
c. Myoglobin and hemoglobin have very similar quaternary
structures.
d. Haemoglobin is a tighter oxygen binder than myoglobin
because it has a different...
Explain why the structure of myoglobin makes it function well as
an oxygen-storage protein whereas the structure of hemoglobin makes
it function well as an oxygen-transport protein. Describe briefly
the two principal models for the cooperative binding of ligands to
proteins with multiple binding sites.
What is the general structure and function of each of the cell
structures:
1. Mitochondria
- What high energy molecule(s) is generated from the
tricarboxylic acid cycle and the electron transport chain?
- Are these aerobic or anaerobic reactions?
2. Ribosomes
3. Endomembrane system
- Endoplasmic reticulum
- Golgi apparatus --what are the forming and maturing faces?
4. Cytoskeleton
- Microfilaments: actin
- Intermediate filaments
- Thick filaments: Microtubules ( centriole, centrosome, cilia),
myosin
5. Nucleus
6. Lysosome
Compare and contrast the primary, secondary, tertiary
and quaternary structures of Myoglobin(Mb) and Hemoglobin(Hb). You
can create a Venn diagram or do columns listing the similarities
and differences. BE SPECIFIC
b) Explain the structure of bone and cartilage
tissues, how this relates to their functions and explain the
differences between them.
c) Explain the key conditions for adequate bone development and
maintenance
describe the actuve location (S) of hemoglobin and myoglobin.
How does the former function to transport 02 from the
lungs to the cells where it is used?
