BIOS 256 Exam 2 Questions with Verified
Correct Answers
6 classes of nutrients
water, carbs, lipids, proteins (macronutrients)
vitamins & minerals (micronutrients)
carbs come in 3 forms
monosaccharides: glucose, galactose, fructose
disaccharides: sucrose, maltose, lactose
polysaccharides: starch, glycogen, cellulose
Catabolism
.
Transfer energy from complex molecules to ATP (breakdown) releases energy
You turn polysaccharides into monosaccharides
lipoproteins classified into 4 categories by density
chylomicrons
very low density lipoproteins
high density lipoproteins
proteins are made of
amino acids
, anabolism
Transfer energy from ATP to complex molecules (building molecules)
minerals and vitamins
minerals are inorganic that plants extract from soil and water
vitamins are organic and necessary for metabolism
water soluble vitamins
Vitamin B and C
fat soluble vitamins
A, D, E, K
3 major pathways of glucose catabolism
glycolysis, anaerobic fermentation, aerobic respiration
glucose metabolism
1. glycolysis
2. formation of acetyle coenzyme A
3. Krebs cycle
4. Electron Transport Chain
electron transport
A sequence of electron carrier molecules (membrane proteins) that shuttle electrons during the
redox reactions that release energy used to make 32 ATP.
