Q

lipogenesis (esterification) happens in

A

adipocytes
muscle cells = IMTG
all fat is stored as energy

Q

lipoprotein

A

transport fat-soluble nutrients to tissues
-as it transfers more fat to tissues, the smaller it gets

Q

liver (chylomicron)

A

where the chylomicron is broken down and made into VLDL

23
Q

VLDL

A

lipoprotein that is made from smaller pieces of chylomicron that was broken down

24
Q

LDL

A

smaller version of VLDL because it has less fat - the cells have been using LPL to take it
-made in the blood vessel

25
HDL
good cholestrol
26
FATP
cell surface transporters- get fatty acid into the muscle cell
27
FABP
chaperone inside muscle cells to mitochondria
28
CPT
transport fatty acids into the mitochondria
29
cholestrol makes
hormones - estrogen, testosterone vitamin D through skin bile - made from liver cell membranes
30
anabolism of membranes
convert FFA into phospholipids
31
fat used during exercise
low intensity plasma FFA from blood IMTG
32
catabolic hormones released at beginning of exercise
glucagon growth hormone
33
growth hormone epinephrine and norepinephrine stimulates
lipolysis
34
adipocyte lipases order
ATGL HSL MGL
35
cellular transport of fatty acids to cell membrane
FATP
36
mitochondrial membrane transport
CPT
37
transport fatty acids in sacroplasm
FABP
38
fate of fatty acids in muscle cell during exercise
FABP transport ACS activation of FA transport into mitochondrai -CPT B-ox krebs etc
39
fat as a fuel MTTATO
mobilization - lipolysis - ATGL,HSL,MGL transport glycerol to liver - to gluconeogenesis transport to cell membrane - FATP, FABP activation - ACS, adding CoA to fatty acid transport into mito - CPTS into mito oixidation - bioenergetics
40
fat max
point of exercise intensity at which you burn the most fat in absolute amounts
41
ketosis
metabolic state characterized by elevated ketone levels in blood or urine
42
ketogenesis
biochemcial process through which ketones are made via catabolism of fatty acids and ketogenic amino acids
43
ketoacidosis
excessive production of ketones leading to acidity of blood, ECF, and ICF
44
prolonged fasting stimulates
lipolysis, beta ox and ketogenesis
45
a keto diet is ___ diet
about 75% of daily intake is fat
46
insulin is an anabolic hormone and promotes storage of
glycogen triglycerides muscle protein breakdown
47
glucagon is catabolic hormone and stimulates
lipolysis which increases blood FFA and stimulates gluconeogenesis
48
glycerol is a substrate for
gluconeogenesis
49
presence of more fat from keto diet
higher use of mito pathways causes increase in NAD and ROS -low glycogen stimulates AMPK
50
benefit of keto diet for athletes
more metabolic flexibility - spares glycogen - uses fat to meet energy demand rather than CHO
51
disadvantages for athletes doing keto
you cant work out at high intensities
52
PDH
enzyme that converts pryuvate to acetyl coa in mitochondria - acetyl coa inhibits PDH
53
EFA recommendations
10: 1 ratio of 6s to 3s
