Q

How many enzyme catalyzed reactions are there in glycolysis?

A

there are 10 enzyme - catalyzed reactions in glycolysis

(optional)
1. Hexokinase transfers a phosphate group from ATP to glucose, making it more chemically reactive.

-> making Glucose-6-phosphate

  • irreversible
  1. Glucose-6-phosphate (aldose) is converted to

fructose 6-phosphate (ketose) by phosphohexose isomerase

  • reversible

–> this step is critical for the next two.

  1. Phosphofructokinase (PFK-1) transfers a phosphate group from ATP to fructose-6-phosphate to yield

fructose-1,6-bisphosphate

-key step for regulation in glycolysis

(PFK-1 is an allosteric enzyme)

  • irreversible
  1. Aldolase cleaves the sugar molecule into two different triose phosphates;
  • glyceraldehyde-3-phosphate (aldose)

-Dihydroxyacetonephosphate (ketose)

  • reversible
  1. Triose phosphate isomerase converts the ketose from last step into the Aldose (glyceraldehyde-3-phosphate)

-reversible

  1. Beginning of payoff phase:

Glyceraldehyde 3-phosphate dehydrogenase (GAPDH) oxidise glyceraldehyde-3-phosphate to

1,3-bisphosphoglycerate (very high energy)+ NADH

-reversible

  1. ATP is generated by substrate level phosphorylation, transferring phosphate group from 1,3-bisphosphoglycerate, making it 3-phosphoglycerate

-reversible, but mostly to the right

  1. Phosphoglycerate mutase relocates the remaining phosphate group from C3 to C2, making it

2-Phosphoglycerate

-reversible

  • important intermediate is generated; 2,3-BPG

= the major allosteric regulator of haemoglobin

  1. Enolase causes a double bond to form in the substrate by extracting a water molecule, yielding Phosphoenolpyruvate (PEP), a compound with a very high potential energy

-reversible

  1. Pyruvate kinase transfer the phosphate group from PEP to ADP forming pryuvate
  • requires K+ and either Mg2+ or Mn2+
  • irreversible

Q

Two stages of glycolysis

A
  1. Energy investment phase (preparatory)
  • glucose molecule is inside cell, and must be kept there. –> produce glucose-phosphate, to destabilise the glucose and then split it
  1. Energy payoff phase
  • oxidise the split molecule, generating ATP and NADH

Q

Regulation of glycolysis can occur via

A

a substrate limited - when concentrations of reactant and products in the cell are near equilibrium, then it is the availability of substrate which decides the rate of reaction

a enzyme limited - when the concentration of substrate and products are far away from the equilibrium, then it is activity of an enzyme that decides the rate of reaction. these reactions are the one which controls the flux of the overall pathway.

Q

Signifigance of ketogenesis and ketogenolysis

A
  1. Early stages of fasting, the use of ketone bodies by heart, and skeletal
    muscle conserves glucose for support of the central nervous system. With more
    prolonged starvation, the brain can take up more ketone bodies to spare glucose
    consumption
  2. High concentration of ketone bodies can induce ketonemia and ketonuria, and
    even ketosis and acidosis

Q

Biosynthesis of triacylglycerols main pathways

A

Three main pathways for triacylglycerol biosynthesis are known:
- sn-glycerol-3-phosphate
- Dihydroxyacetone phosphate pathways

100
Q

Eicosanoid Hormones

A
101
Q

Flipases, EC and IC

A
  • Selective translocation of PC to the ER lumen occurs. This becomes the plasma membrane

EC - rich in PC and SPH

IC - rich in PE and PS

101
Q

How is HMG-CoA reductase controlled in transcription, translation and posttranslational modifications?

A

Transcription - mRNA synthesis is inhibited by food cholesterol

Translation - HMG-CoA reductase synthesis is inhibited by non-ster derivatives of mevalonic acid

Posttranslational modification - increased level of cholesterol and/or mevalonic acid stimulates phosphorylation of HMG-CoA reductase –> enhancing degradation by proteases

102
Q

Biological significance of cholesterol

A
  • an essential lipid constituent of cell membranes
  • a precursor of steroid hormones and of bile acids
  • intermediates of cholesterol biosynthesis are required to make vitamin D and for posttranslational modification of membrane proteins
  • high plasma cholesterol promotes atherosclerosis
102
Q

Formation of Δ3 -Isopentenyl pyrophosphate

A

First its Melalonate, then with the help of mevalonate kinase and phosphomevalonate kinase it becomes 5-pyrophosphomevalonate. This with the help of pyrophosphomevalonate decarboxylase further becomes Δ3 -Isopentenyl pyrophosphate.

103
Q

Processes that determine the cholesterol balance

A
  • intestinal uptake of dietary cholesterol
  • de novo cholesterol synthesis
  • synthesis of steroid hormones from cholesterol
  • synthesis of bile acids from cholesterol, and their billary secretion
  • bilary secretion of surpus cholesterol in unmodified form
103
Q

Formation of dimethylallyl pyrophosphate

A

Isopentenyl pyrophosphate becomes dimethylallyl pyrophosphate with the help of isomerase

104
Q

De novo synthesis of cholesterol, where is it? what is the equation?

A

Primary site: liver

Secondary sites: adrenal cortex, ovaries, testes

104
Q

Synthesis of farnesyl pyrophosphate

A

Geranyl pyrophosphate becomes Farnesyl pyrophosphate with the help of geranyltransferase

105
Q

Major roles of complex lipids

A
  1. energy
  2. membranes
  3. hormones
  4. cell-signaling
105
Q

Lanosterol formation

A

2x farnesyl pyrophosphate becomes squalene with the help of squalene synthase. Squalene goes through cyclization and becomes lanosterol

106
Q

What in the liver parenchymal cell is involved in the synthesis of ketone bodies?

A

Mitochondrial HMG-CoA synthase

106
Q

How many steps does the conversion of lanosterol to cholesterol require?

A

It requires 19 separate steps

107
Q

Conversion of HMG CoA to activated isoprenoids

A

HMG CoA reductase catalyzes mevalonic acid

Reaction catalyzed by the enzyme is the rate-limiting reaction.

The enzyme is the target of statins which inhibit the activity of HMG-CoA reductase.

(the statins can decrease total plasma cholesterol and LDL-cholesterol even by 50%)

107
Q

De novo synthesis of cholesterol in short:

A

Stage 1: Forms HMG CoA

Stage 2: Forms activated 5 carbon intermediates (isoprenoids)

Stage 3: Six isoprenoids form squalene

Stage 4: Squalene + O2 form cholesterol

108
Q

What is energy dissipation in the liver thought to contribute to

A

The 6p expended for every 2p produced causes weight loss

108
Q

Fasting vs feeding cholesterol synthesis

A

Feeding promotes cholesterol synthesis

Fasting inhibits cholesterol synthesis

109
Q

Regulation of Acetyl-CoA carboxylase
Global vs Local

A

Global:
+ insulin
- glucagon
- epinephrine

Local:
+ citrate
-Palmitoyl-CoA
-AMP

109
Q

Types of bile acids/salts

A

Primary bile acids
- good emulsifying agent
- all OH on the same side
- pKa = 6

Conjugated bile salts
- amide bonds of glycine or taurine
- very good emulsifier
- pKa lower than bile acids

110
Q

Synthesis of bile salts

A
  • Hydroxylation
  • side chain cleavage
  • conjugation
  • secondary bile acids
110
Q

LDL receptor deficiency

A
  • gene for LDL is on chromosome 19
  • no gender difference
  • Mutation is recessive
  • 420 different mutations identified (dominant trait)
  • activity 0 - 25% of normal

Q

Heterozygous FH vs Homozygous FH

A

Heterozygous FH:
- 1/500
- Hypercholesterolemia

Homozygous FH:
- 1/1 000 000
- Extremely high LDL - cholesterol

112
Q

Types of steroid hormones

A
  • Glucocorticoids; cortisol is the major representative in most mammals
  • Mineralocorticoids; aldosterone being the most prominent
  • Androgens such as testosterone
  • Estrogens, including estradiol and estrone
  • Progestogens (also known as progestins) such as progesterone
113
Q

Steroid hormones are derived from…

A

Cholesterol

114
Q

Two important facts about steroid hormones

A

They are freely permeable to membranes so they are not stored in cells

They are not water soluble so they have to be carried in the blood complexed to specific binding globulins

115
Q

Functions of steroid hormones

A
  • carbohydrate regulation (glucocorticoids)
  • mineral balance (mineralocorticoids)
  • reproductive functions (gonadal steroids)

also play roles in inflammatory responses, stress responses, bone
metabolism, cardiovascular fitness, behavior, cognition, and mood.
