BODY WATER COMPARTMENTS - PART C

1) Why closely observe a patient following electrocution (eg. lightning strike) or concussion?

2) What is the force driving simple (passive) diffusion?

3) What is the difference between simple diffusion and facilitated diffusion?  Give an example of a substance which is transported by facilitated diffusion.

4) Explain the direction and ratio of ion transport by the Na+/K+ ATP-dependent pump.

5) Is Na+ transport by the Na+/K+ ATP-dependent pump an example of primary or secondary active transport.  Explain.

6) Give an example of a secondary active transport mechanism.  What is the difference between secondary and primary active transport?

7)  Identify at least 2 major functions of the ER.

METABOLISM - PART A (which is the only part, by the way!)

1) What is meant by the terms aerobic versus anaerobic?  Are you an aerobic or anaerobic organism?

2) What is the purpose of glycolysis?

3) What are the useful by-products of aerobic versus anaerobic glycolysis?

4) Where does glycolysis take place?

5) How many pyruvate are produced by glycolysis of a single glucose molecule?

6) Before pyruvate can enter Kreb's cycle, pyruvate must be converted to......?

7) What are the useful by-products of conversion of pyruvate to acetyl CoA?

8) Where does Kreb's take place?  Is it aerobic or anaerobic?

9) What are the useful by-products of Kreb's?

10) How energetically efficient is Kreb's?  What do you see as the real purpose of Kreb's?

11) Where do the ETC reactions take place?  Are they aerobic or anaerobic?

12) What do i) glycolysis, ii) the conversion of pyruvate to acetyl CoA and iii) Kreb's cycle all donate to the ETC?

13) What is the purpose of the ETC?

14) Explain, to a child, how the ETC is able to produce ATP... be sure to include the following terms in your explanation... enzymes, electrons, proton, pump, inner mitochondrial membrane, inter-membrane space, mitochondrial matrix, concentration gradient, ATP synthase, energy.

15) How many ATP are produced for each NADH and FADH₂ that enter the ETC?

16) What is the purpose of the the Cori cycle and where does it take place?  What happens to the Cori cycle if this organ fails?  What would failure of the Cori cycle mean in terms of the development of an acid-base imblance?
