6. What is a function for glyceraldehyde 3-phosphate
- It acts as an intermediate in glycolysis and gluconeogenesis
- It acts as an intermediate in lipolysis
- It acts as an intermediate in the TCA cycle
7. Fat oxidation can be summarised into three simple steps. What is the 3rd step?
- Fatty acids are broken down step by step to acetyl CoA to enter the TCA cycle.
- Lipids must be mobilised from adipose tissue. TAG is degraded to fatty acids & glycerol
- Lipids must be mobilised from adipose tissue. TAG is degraded to fatty acids & glycerol
8. Which of the following best describes beta oxidation?
- The oxidation of fat molecules using Beta enzymes
- The sequential removal of 2 carbon fragments from a fatty acid
- The adding of oxygen molecules to triglyceride compounds
9. Transport of FFA across the cell membrane into muscle cells occurs through:
- Active cotransport
- Diffusion
- Facilitated diffusion
- Active transport
10. Fat oxidation can be summarised into three simple steps. What catalyses the reaction in the first step
- Hormone sensitive lipase
- Fatty acyl-CoA synthase
- Lipolase
11. Fat oxidation can be summarised into three simple steps. What is the 2nd step?
- Fatty acids must be taken into the cell, activated and transported into the mitochondria for further degradation.
- Lipids must be mobilised from adipose tissue. TAG is degraded to fatty acids & glycerol
- Fatty acids are broken down step by step to acetyl CoA to enter the TCA cycle.
12. What happens to the glycerol compounds formed in the breakdown of triglycerides
- They are absorbed by the liver
- They are absorbed into the bloodstream
- They are immediately recycled and used for the reesterification of triglycerides
13. FFA are converted to CoA derivative in preparation for Beta Oxidation. What else does this priming reactin require?
- Oxygen
- Carbon dioxide
- ATP
- Water
14. Fat oxidation can be summarised into three simple steps. What is the 1st step?
- Lipids must be mobilised from adipose tissue. TAG is degraded to fatty acids & glycerol
- Fatty acids must be taken into the cell, activated and transported into the mitochondria for further degradation.
- Fatty acids are broken down step by step to acetyl CoA to enter the TCA cycle.
