How does exposure to CO affect the loading and unloading of oxygen by haemoglobin?

- exposure to CO linits the maximum % saturation of O2 to only 50%

- at a lower ppO2, Hb has a higher affinity for O2

- Hb unloads less O2 at low ppO2

How do you say no statistical test in evaluation Qs?

- no statistical test to show if differences are significant

What can be the purpose of boiling a bacteria agar?

So there is no contamination

What is the purpose of boiling an enzyme?

To denature it to stop reaction bcs no more E-S complexes

What is the purpose of transferring the same volume of liquid culture onto each agar plate? - specifically the bacteria Q

- so the same number of (bacteria)- to allow comparison

Explain the advantages of lipid droplet and Michelle formation.

- droplets increase SA

- for faster digestion

- micelles can carry FA & MG to the epithelial cell

How is the Golgi apparatus involved in the absorption of lipids?

modifies and processes triglycerides by adding glycoprotein to them

Then cholesterol is added to them . they are packaged for release in chylomicrons to leave the cell through exocytosis.

What happens when E-S complexes are formed?

The bonds in the enzyme’s active site are bending

When acid, alcohol, etc are used in a membrane, what happens to it?

It becomes more permeable, perhaps breaks down

What forms ATP?

adenine, 3 phosphates, ribose sugar, ATP synthase

When exhalation happens, what happens to intercostal muscles?

Internal intercostal muscles relax

What happens to CO2 when abdominal pumping?

Released high due to high pressure changes

Why is there a low concentration of O2 in insects?

Respiring cells and closed spiracles
