BMS100 BCHM EXAM QUESTIONSAND ACCURATE ANSWERS
covalent vs non-covalent - Answer - shaping of electrons
- non-polar: equal sharing
- polar: non equal sharing
purpose of fats (4) - Answer - protect organs
- give body shape
- fule
- makes membranes
saturated vs non-saturated fatty acids - Answer - S: all single bonds
- Non-S: loss of H causing a double bond
branch chained aa - Answer - valine, leucine and isoleucine
- liver cannot degrade them
nucleotide composition - Answer - phosphate group
- ribose (5C sugar)
- nitrogenous base
types of nitrogenous base - Answer - Purines: adenine, guanine
- Pyrimidines: cytosine and thymine
anabolsim definition - Answer - uses energy to make something
anabolsim reaction (6) - Answer - Gluconeogenesis: building glucose from lactate,
glycerol and aa),
- glycogenesis: building of glycogen)
- fatty acid synthesis: building of fatty acids from acetyl-CoA
- lipogenesis: building of triglycerides
- ketogenesis: building of ketone bodies)
,- pentose phosphate shunt: uses glucose to make 5C and NADPH)
Catabolsim definition - Answer - breaks things down to make energy
catabolism reaction (6) - Answer - glycolysis: break down of glucose to pyruvate
- glycogenolysis: break down of glycogen to glucose
- beta oxidation: break down of fatty acids into acetyl- CoA
- lipolysis: break down of lipids/tri-glycerides
- ketolysis: break down of ketone bodies)
- Krebs cycle (makes ATP, NADH, NADPH from pyruvate)
ketone bodies - Answer - source of last resort energy for the brain that the liver makes
- acetoacetate, beta-hydroxybutyrate, and acetone
ATP composition - Answer - adenosine, ripose, 3 phosphates
ATP purpose+facts - Answer - direct cell energy
- building block for RNA and DNA
- make in mitochondrial matrix
- cannot get out of the cell
reduced cofactors - Answer - indirect cell energy
- NADH (from B3) and FADH2 (from B2)
- reduced in Krebs cycle/glucose -> lactic acid in RBC
- oxidized in the ETC
Macronutrients (3) - Answer - lipid
- proteins
- carbohydrates
amino acid break down - Answer - makes H2O, CO2 and NH3 (toxic)
- ATP needed to convert NH3 to urea
- do not store extra aa and break them down if we need energy
lipid stores - Answer - triglyceride
carbohydrate stores - Answer glycogen
, NADPH - Answer - used to keep NADH levels in cytosol
Ways that acetyl-CoA is made (3) - Answer - glycolysis: glucose-> 2 pyruvate -> matrix ->
2 acetyl CoA
- ß-oxidation: fatty acid -> acetyl CoA
- Ketolysis: non-liver tissues ketone bodies -> acetyl-CoA
Things that are made with acetyl-CoA (2) - Answer - generates ATP, NADH, FADH2 in
krebs cycle
- makes ketone bodies in the liver
Co-enzyme A - Answer - very large enzyme that carries the acetyl group
- derived from B5
- thioester linkage to acetyl group
- also added to fatty acid (fatty acyl-CoA) trapping it in cell and making it more water
soluble
aerobic respiration - Answer - in the precence of O2
- breakdown of glucose to produce energy via ETC
anarobic respiration - Answer - without O2
amino acids that are ketogenic - Answer leucine and lysine
amino acids that are both keto and glucogenic - Answer threonine, tyrosine, tryptophan,
phenylalanine, isoleucine
beri beri - Answer - low levels of thiamine (B1)
- tired, tachycardia, numbness, lung congestion, edema
Lipid soluble vitamine (4) - Answer - A: retinol
- D: calciferol
- E: tocopherol
- K: phytonadione
water soluble Vitamins - Answer - B1-3, 5-7, 9, 12
-C
[H+] in pure water - Answer - 1x10-7
- pH 7
