Q

what is the function of metabolism

A

obtain chemical energy from degradation of food

convert compound precursor molecules in order to build carbohydrate, lipid, and protein

anabolism- the biosynthetic phase buildup of metabolism, which requires energy

catabolism - the degradative phase of metabolism(break down) which is accompanied by the release of energy energy producer release energy

Q

carbohydrates cabolism overviews

A

glycolysis break it down glucose (happen in cytoplasm
make atp
turn it into pyruvate > no oxygen turn into lactate. > with oxygen goes into mitochondria & make acetyl COA

Q

when Atp looses a phosphate become

A

become ADP
the left over / excess ADP signal to activate to make atp

VIA respiratory chain

Q

RESPIRATORY CHAIN IS THE

A

electron transport and oxidative phosphorylation = give energy to phosphate to bind with ADP =atp

happen in mitochondria (cellular respiration )

electron transport give hydrogen ion energy to bind with oxygen to form WATER & 3 molecules of atp

Q

citric cycle explain

A

sequence of 8 reaction
involve breakdown of activated of two carbon that residue/inside ACETYL COA > that are break into 4 Hydrogen to enter respiratory chain

***those hydrogen is what bond to O2 to form water in respiratory chain

Q

active of acetyl

A

lactic acid (no O) >SOK(which releases H+ goes in respiratory chain > pyruvic acid release CO2 & hydrogen which turn into COA > goes in kreb cycle ( give 3)
then 12 atp

19
Q

Glycolysis

A

Degration of glucose to yield lactic acid or pyruvic acid

20
Q

Gluconeogenesis & where it’s at

A

synthesis of new glucose from non-carbohydrate persecutor, such as pyruvic acid or lactic acid

amino acid glycerol

21
Q

glycogenesis & where it’s from

A

synthesis of glycogen from glucose

liver muscle tissue activated by insulin

22
Q

the complete oxidation of glucose yield to make

A

pyruvic acid >goes kreb cycle to make 36 atp

23
Q

lipid function

A

energy
insulation
shock absorber

24
Q

lipid are store in what tissue

A

adipose tissue

25
triacyglycetolys > hydrolysis give
glycerol + fatty acid
26
lipid or fatty ass forms with protein call ? & transport by
call lipoprotein transport by blood
27
pyruvic acid is where in the body
liver
28
carbohydrate digestion steps
mouth +a - amylase . = break, polysaccharide and disaccharides. into smaller small intestine - pancrease realease - A amylase & breaking enzyme > turn into monosaccharide > small intestine absorb to bloodstream (monosaccharide)
29
lipid break down
begins in mouth Stomach (chyme) Small intestine- bile acid (emulsification) & pancrease lipase-breakdown fatty acids triglyceride> put in bloodstream
30
B oxidation step
de hydrogenation -remove to H unsaturated fatty COA goes to respiratory chain atp Hydration -hydroxlyacyl COA oxidation removed to H -ketoacyl coa >respitory chain atp cleavage - acety coa > kreb cycle >atp
31
atps made
glucose 36 gycerol 20 stearic acid 146 palmitic acid 129
32
keaton bodies
produce when the concentration of COA buildup and accumulates in the liver because of the B oxidation over production of COA IN LIVER VIA B OXIDATION
33
chronic starvation
low carbohydrate
34
human require how much amino acid
20 amino
35
essential amino acid must be supplied in the ??
diet because they cannot be synthesized by the organism (9a)
36
non-essential amino acid can be synthesized by the
organism
37
Glucose tolerance
organism keep blood glucose level under control
38
glucagon
A peptide hormone, secret / release by pancreas that stimulate glycogenlysis
39
Insulin
peptide hormone that helps remove glucose from the bloodstream by stimulating glycogenesis insulin is produced by the pancreatic b cells
40
diabetes is
abnormally high blood course due to insufficient insulin production
41
symptom of glucose
chronic hyperglycemia glucosuria hunger thirst weight loss acidosis blindness
42
type 1 diabetes
beta cell stop producing insulin & can be control
43
type 2 diabetes
can be produced but cells dont respond to it , need life style change &
44
nitrogen pool
sum of all the nitrogen compounds in body
45
nitrogen pool made of polypeptide > hydrolysis >
free amino acid free amino acids
46
negative nitrogen positive nitrogen
excretion > protein intake tissue destruction protein intake > excretion growin child
47
how much energy release per at molecules
7.3 kal/mol
