Do we have evidence that amylase can effectively digest starch in the mouth? Say yes or no. If yes, explain what the evidence is from this experiment. If no, explain what results in our experiment would have to be different to give us this evidence.
In the Alanine Cycle, different organs work together to produce glucose from protein. Which statement below best describes what happens in which organ?
a)In liver, pyruvate is transaminated to alanine; in the muscle, alanine is deaminated and pyruvate is used for ATP synthesis.
b)In muscle, pyruvate is transaminated to alanine; in the liver, alanine is deaminated and pyruvate is used for gluconeogenesis.
c)The liver exports glucose for use by the brain; in the muscle, alanine is deaminated by the urea cycle for use in ATP generation.
d)In muscle, pyruvate is transaminated to alanine; in the liver, alanine enters the urea cycle for excretion.
Using specific examples from your learning in biochemistry, explain how glucose breakdown, storage and synthesis occurs and how it is regulated in humans
