Objectives
By the end of this exercise you should be able to:
Explain why a very low blood glucose concentration causes loss of consciousness
Explain why the brain has a relatively large requirement for metabolic energy
Describe how sodium and potassium ions can be transported against their concentration gradient and explain the role of ATP in this process
Describe how endothermic reactions can be driven in the thermodynamically unfavoured direction linked to the hydrolysis of ATP to ADP and phosphate
Describe the role of ATP in muscle contraction
Explain the role of coenzyme A in metabolism
Explain how it is that sequestering coenzyme A can lead to severe metabolic disturbance and profound hypoglycaemia
