IB Cell Biology

Carbohydrates are made up of ❌

The ❌ attraction of ❌ quantities of water molecules can interrupt ❌ ❌ and result in the ❌ of the ❌.

Drag and drop the correct functions and uses to the correct -saccharides.

Glucose: ❌
Galactose: ❌
Fructose: ❌
Lactose: ❌ and found in milk
Maltose: broken down by starch and is ❌
Glycogen: Insoluble storage of glucose in the liver, ❌
Starch: ❌
Cellulose: ❌

Sort the following statements into competitive and non-competitive inhibitors.

Competitive
- Increasing the inhibitor concentration ❌
- Competes with the ❌ at the active site
- Active site ❌

Non-Competitive
- Increasing the inhibitor concentration ❌
- Inhibitor ❌ at the active site
- Active site ❌

Match the stem cells with their functions.
Totipotent - Can differentiate ❌
Pluripotent - Can differentiate ❌
Multipotent - Can differentiate ❌
Uni-potent - Can differentiate ❌

Match the following with their correct functions.
❌: for passage through the membrane
❌: for ❌ across the membrane. (using energy from ATP)
Electron carrier proteins: a chain of ❌ proteins that allow electrons to pass through the ❌
Enzymes held in the membrane: ❌ reactions at the surface of the membrane. (within or outside of the cell)
❌: the substrate molecule fits here and the reaction then occurs
Binding protein for attachment of a specific ❌: a signal is then generated that is transmitted inside the cell
cell-cell recognition site: - attachment may result in cells ❌ together
❌: for antigen-❌ reaction
