What specifically is this biochemical used for, and how is it broken down during digestion?
Cerrena [4.2K]
Digestion occurs in the stomach and the duodenum through the action of three main enzymes: pepsin, secreted by the stomach, and trypsin and chymotrypsin, secreted by the pancreas.During carbohydrate digestion the bonds between glucose molecules are broken by salivary and pancreatic amylase.The digestion of certain fats begins in the mouth, where short-chain lipids break down into diglycerides because of lingual lipase. The fat present in the small intestine stimulates the release of lipase from the pancreas, and bile from the liver enables the breakdown of fats into fatty acids.DNA and RNA are broken down into mononucleotides by the nucleases deoxyribonuclease and ribonuclease (DNase and RNase) that are released by the pancreas.

The mitochondrion, like the nucleus, has two or more membrane layers. How is the innermost of these layers different from that o
tensa zangetsu [6.8K]

Answer:

The double membrane of the mitochondria is highly folded,and therefore wider when unfolded than that of the nucleus.This is an adaptive feature  to increase the surface area for reactions (electrochemical  gradient) by accommodating protons pumped into it by the proton motive force(PMF)  from the matrix to set up the electrochemical gradients needed to generate the energy needed by ATPase synthase enzymes for ATPs synthesis.

Required number of protons needed to be accommodated by the double membrane to generate enough energy for ATPase synthesis,therefore larger surface area is needed.

What protein (purine)-rich food should be limited to prevent a reoccurrence of uric acid kidney stones? what protein (purine)-ri
Nataliya [291]

Answer:

Eggs

Explanation:

Uric acid stones are one of the four types of kidney stones which are formed due to the high amount of uric acid in the human body.

When the concentration of the uric acid increases in the urine due to which urine becomes acidic, the uric acid gets stored in the urinary pathway in the form of stones.

To remove the uric acid kidney-stones, the food rich in purines must be avoided like meat, eggs and green vegetables like mustard, spinach, and whole grains are suggested.

Thus, the egg is the correct answer.
