BIOCHEM LEC FINALS

give 3 functions of an enzyme:

• protein that catalyzes chemical reactions and is catalyzed by ph, temp, and concentration

• speeds up reaction progress with same outcome

• helps regulate metabolism

• only found in animals

pairs of reactions that occur together

• coupled reactions

• energy

• opposites

released by absorption of the other

• coupled reactions

• energy

• opposites

space between outer and inner membrane

• intermembrane space

• matrix

enclosed by the inner membrane

• intermembrane space

• matrix

is the first step - catalyzed by enzymes in the saliva, stomach, and small intestines.

• digestion

• carbohydrates

• protein

• triacylglycerols

hydrolyzed into monosaccharides beginning with amylase enzymes in saliva and continuing in the small intestine

• digestion

• carbohydrates

• protein

• triacylglycerols

digestion begins when stomach acid denaturesthe protein and pepsin begins to xleave the large protein backbone into smaller peptides.

• digestion

• carbohydrates

• protein

• triacylglycerols

emulsified by bile secreted by the liver, then hydrolyzed by lipase into 3 fatty acids and a glycerol backbone

• digestion

• carbohydrates

• protein

• triacylglycerols

monosaccharides, amino acids, and fatty acids are degraded into acetyl groups, which are then bonded to coenzyme A forming acetyl-CoA

• Formation of acetyl CoA

• Citric acid cycle

• Electron acid chain and oxidative phosphorylation
