(Energy) production Flashcards
PPP produces
NADPH⁺
glycolysis energy gain (per glucose molecule)
CYTOPLASM
2 ATP is used
4 ATP is produced (substrate level phosphorylation)
2 NADH -> ATP (oxidative phosphorylation)
pyruvate energy gain
2ATP (substrate level phosphorylation)
how many TCA cycles per glucose molecule?
MITOCHONDRIA
2 acetyl-CoA molecules are produced from each glucose molecule, two cycles are required per glucose molecule
Production per TCA cycle (per AcCoA)
- ETC and chemoismosis
3 NADH (9ATP) (oxidative phosphorylation)
FADH2 (2ATP) (oxidative phosphorylation)
1 GTP
=12ATP per AcCoA
(3 H+, CoA-SH, 2 CO2)
total net ATP production per glucose molecule
36 ATP, 38 without the 2 used in glycolysis
localization of de novo and degredation of pyrimidine nucleotides
cytoplasm of all cells
regulatory enzymes of pyrimidine nucleotide de novo
eu: carbamoylphosphate synthetase II
pro: aspartate-carbamoyl transferase
energy needed for pyrimidine synthesis
UTP: 6ATP
CTP: 7ATP
complete oxydation of one glucose molecule in PPP requires how many cycles
6 cycles
PPP; function of oxidative part vs. non- oxidative
ox: NADPH+H⁺ production
nonox: complete ox of one glucose molecule and metabolize pentoses from NA from digestion and recombination
PPP localization
cytoplasm of all cells in
- adipose tissue
- liver
- mammary gland
- erythrocytes
regulatory enzyme of PPP
Glucose-6-P dehydrogenase
energy production of PPP
6*2 NADPHH -> 24 ATP in cytoplasm
localization of fructose synthesis
placenta, seminal vesiculum in ungulates
localization of fructose degradation
mostly in sperm and fetus of ungulates
lactose synthesis localization
mammary gland
galactose synthesis localization
bone, cartilage, mammary gland
oxidative deamination where
mostly liver, mitochondria
where is haemoglobin synthesized
liver, bone marrow
glycolysis: how many times per glucose molecule?
2 times per molecule
B-oxidation of even FA location
liver, muscle; mitochondrial matrix
location of FA synthesis
cytoplasm: liver, adipose tissue, mammary gland
energy balance of ketogenesis
2AcCoA: - 2*12ATP
NADPH+H⁺: - 3ATP
= -27ATP
where does ketogenesis occur
mitochondrium of liver, kidney and mammary gland
where is cholesterol synthesized
cytoplasm: liver, gonads, intestines
lipid synthesis in ruminant
mammary gland and adipose tissue - not liver!!
ascorbic acid synthesis
liver
birds: kidney
