Of a monogastric stomach, the 1st of the four regions is called esophageal region that can secrete mucus, HCl, and a few digestive enzymes.

After amino acid catabolism, the carbon skeletons of the following amino acids can join TCA cycle to produce energy: (A) Phenylalanine(B) Valine(C) Serine(D) Threonine(E) All of these 4 amino acids

Which compartment of ruminant stomach absorbs relatively a large quantity of water?

Where does the Electron Transport Chain take place? In mitochondria In cytosol In smooth endoplasmic reticulum In both mitochondria and cytosol In both mitochondria and endoplasmic reticulum

Small intestinal epithelial cells can not only absorb free amino acids, but also can absorb di- and tri-peptides.

An endopeptidase cleaves the peptide bonds in the middle of the amino acid chain (i.e., the middle of a protein) to form multiple peptide fragments.

The first enzyme that is needed for the first step of glycolysis pathway is Phosphohexose isomerase Phosphofructo- kinase Hexokinase Fructose 1,6-bisphosphate aldolase Triose phosphate isomerase

From animal nutrition standpoint, please describe the concept of ideal protein and also the concept of “first limiting amino acid”.  Why the first limiting amino acid is so important?
