gluconeogenesis

why carbohydrates are of vital importance for the human body?

• they store energy in the form of glycogen

• they produce fatty acids for energy

• they produce energy neccesary for the body (ATP)

where are the sites in which gluconeogenesis takes place? Mark all that apply

• Liver

• bones

• adipocytes

• kidneys

• intestines

metabolic pathways of carbohydrates, mark all that apply

• glycolysis

• gluconeogenesis

• glycogenolysis

• beta oxidation

what are the ingredients neccesary to cook some glucose in gluconeogenesis?

• ATP and lipids

• ATP and fatty acids, and proteins

• ATP, lactate, glycerol and all amino acids except leucine and lysine

• ATP, glycerol, phospholypids, lactate

What enzyme is responsible for converting pyruvate to oxaloacetate?

• pyruvate dehydrogenase

• pyruvate decarboxylase

• pyruvate kinase

In order for oxaloacetate to pass from the mitochondria to the cytosol, it must be transformed into:

• glycerol

• malate

• ketoglutarate

• lactate

the 3 stress hormones responsible of enhancing the activity of PEPCK to catalyze PEP -- Choose all that apply

• adrenaline

• ephinephrine

• cortisol

• glucagon

the second roadblock in gluconeogenesis is ...........

• transform PEP into DHAP

• transform oxaloacetate into PEP

• transform fructose biphosphate into glucose

• transform glucose 1,6 phosphate into glucose 6 phosphate

the third roadblock in gluconeogenesis

• converting fructose 6 phosphate into glucose 6 phosphate

• converting oxaloacetate into malate

• converting fructose 1,6 bisphosphate into fructose 6 phosphate
