Test strips for urine glucose contain

glucose oxidase and peroxidase
amylase
insulin
Benedict’s reagent
4.
Saltatory conduction occurs because:
Axons are wider
Temperature is higher
Myelin restricts depolarisation to nodes of Ranvier
K+ channels are absent
5.

Depolarisation during an action potential is caused by

voltage-gated sodium ion channels opening and Na⁺ diffusing in
K⁺ diffusing out
Na⁺ being pumped out
Ca²⁺ leaving
6.
The refractory period ensures that:
Impulses travel in one direction
Action potentials are larger
Myelin forms
Na+ channels stay open
7.
In multiple sclerosis, myelin is damaged. Using the table, what happens to conduction speed?
It rises
It falls greatly
It stays at 100 m/s
It becomes chemical
