What is a form of allosteric regulation that can amplify enzyme activity?

• Cooperativity

• carbon dioxide

Hypertonic solution :

• A/ no net water movement

• B/ cell may loses water

• C/ cell gains water

What can ATP transfer?

• oxygen

• hydrogen

• Phosphate

• carbon dioxide

Who is from high to low consentrotion?

• Facillitated diffusion

• pump

• passive

• transport

Who need ATP?

• Active

• passive

• diffusion

• endocytosis

- How the cell support influx of substrate ?

• cell produce more enzymes

• cell produce less enzyme

• The cell does not produce an

  enzyme

A cell does switching by on or off the genes that.......

• encode specific enzymes

• regulating the activity of enzymes

• all of them

Allosteric enzymes are very important in

• feed back regulation

• feed back reregulation

• 6

• 8

• 10

• 7
