There is an enzyme called amylase which is present is saliva and helps in the breaks down carbohydrates present in our food thereby converting it to glucose. When the glucose reach in body’s small intestines, there are some air ball like structures called microvilli that absorb the glucose the into the bloodstream.
This glucose present in bloodstream triggers the beta cells present in the pancreas and stimulate the production insulin. As we know that, the diabetes in actual is the lack of insulin receptors or insulin. However, if there is glucose in the blood but enough amount of insulin is not present, it will limit the uptake of glucose and instead a part of kidney called glomerulus will take the glucose from blood stream. The kidney will ultimately filter out this glucose when the person will urinate. This causes wastage of body’s glucose and also causes organ and tissue damage to the person suffering from it.
Nitrogen Fixating bacteria ( such as cyanobacteria or clostridum) can convert gaseous nitrogen in the air into amonia, a compound that organism can use to make amino acid and other nitrogen-containing organic molecules
Cellular respiration is defined as a ATP generating process in which organic molecule is oxidized and inorganic molecule is final electron acceptor
Pain experienced in leg muscles is the result of formation of lactic acid in muscle cells
Under low oxygen, NADH cannot be reoxidized to NAD+ but NAD+ is required as an electron acceptor to continue glycolysis
In lactic acid fermentation pyruvate is the final electron acceptor and converted in lactate
Reaction catalyzed by lactate dehydrogenase
The pain in her chest is caused from the lack of oxygen she received while running so her chest starts to heavily breathe so that the lungs can receive as much oxygen possible
