The enzyme must attract substrates to its active state.
At the end of the reaction, products dissociate from the surface of the enzyme
Answer:
E) 4,6,7,1,2,3,5
Explanation:
- The correct sequence of events is as follows.
- A grated depolarization brings an area of excitable membrane to a threshold.
- Sodium channels are activated and open, allowing positively-charged sodium ions to pass through.
- The sodium ions then enter the cell, and depolarization of the negatively-charged cell membrane is initiated.
- Sodium channels are first inactivated.
- The voltage-gated potassium channels then open, allowing for potassium ions to move out of the cell, initiating repolarization.
- Sodium channels then regain their normal properties allowing the sodium ions to pass through and making the cell membrane repolarized again.
- The cell membrane will reach its resting membrane potential again.
- Afterward, a temporary hyperpolarization occurs.
Riley can either change the surface area of the object or can change the slipperiness of the material.
