Because of the presence of both activation and inactivation gates, voltage-gated Na channels can be all of these.
- Sodium voltage-gated channels can be either closed, open, or inactive.
- Voltage-gated sodium channels are closed when at rest. Both an activation gate and an inactivation gate are present in voltage-gated sodium channels.
- Although the inactivation gate is open, the activation gate is closed. This conformation is closed but capable of opening. Some of the activation gates open as a result of membrane depolarization brought on by a stimulus.
- Both the activation and inactivation gates will be opened at this point. As sodium ions enter the cells, nearby activation gates will open.
- A greater amount of sodium will enter the cells as a result, initiating an action potential.
- Both gates open when certain depolarization thresholds are reached. Action potential increases to its maximum as sodium rushes into the cell.
- The inactivation gate will gradually close and the permeability of the membrane to sodium ions will decrease. The channel is now in a state known as "closed but not capable of opening."
- Up until the membrane potential reaches its resting state, this occurs. The channels once more assume the "closed but capable of opening" conformation when resting values are attained.

Explanation:
Thutmose III ("the Napoleon of Egypt": reign 1479–1425 BC) expanded Egypt's army and wielded it with great success to consolidate the empire at the peak of Egypt's power and wealth during the reign of his successors Amunhotep II (reign 1427–1401 BC or 1427–1397 BC), Thutmose IV (reign 1401 – 1391 BC or 1397 – 1388 BC)
Answer and explanation:
Antibodies are structures made of four polypeptides, <em><u>two light (L) chains and two heavy (H) chains that join together and form a molecule shaped like a "Y"</u></em>. This structure is possible thanks to the <u>disulfide bonds</u> that bind light chains and heavy chains together. While the stem of the Y is constant and doesn't change ("<em>constant region</em>"), the tips of the Y, composed of 110-130 amino acids and called "<em>the variable region</em>", vary greatly among the different antibodies and are responsible for the high specificity of these molecules.
<u>This is why we could say that the primary structure of this protein is given by disulfide bridges that twist the antibody and allow it to bind to a protein from the flu virus.</u>
Answer:
You are wandering the aisle at target trying to choose which laundry detergent to get. You decide to get one on a compostable, paper-based bottle since you are trying to reduce your plastic consumptions. Once you get home you notice that the detergent itself is packaged in a plastic liner within the paper, compostable botte. This deceiving packaging is an example of _________.
