€‹how do sodium and potassium travel into and out of cells? ​antidiuretic hormone transports potassium and prodiuretic hormone carries sodium. ​specific transport proteins in the blood deliver the minerals to the cell cytoplasm. ​the balance of insulin and glucagon determines the movement of these minerals into and out of cells. ​transport proteins within the cell membrane pick up and release the minerals across the membrane. a negative feedback loop uses blood glucose levels for transfer.​

The correct answer is "transport proteins within the cell membrane pick up and release the minerals across the membrane".
Sodium and potassium travel in and out of cells with the help of sodium-potassium adenosine triphosphatase (or Na+/K+ ATPase). This is a transmembrane ATPase, meaning that it is an enzyme located in the cellular membrane of all animal cells. It works as a pump, by pumping sodium out of the cells while pumping potassium out of the cells.

True. Carbohydrates readily provide energy anaerobically.

Explanation:

Carbohydrates, proteins and fats all combined provide energy to the body. But whenever our bodies need energy, out of the three carbohydrates are first used to provide it.

Carbohydrates include starch, sugar etc are readily broken down into glucose to fulfil the bodies energy requirements. Blood sugar is one of the most significant energy sources for the body to provide energy to the body at rest or while working. It’s also serves as an energy supply to the brain.

Digestion begins from the mouth. Our bodies release certain enzymes to breakdown food. Then each of our body cells comes in and uses the finished product aerobically or anaerobically into Adenosine triphosphate depending on the need. ATPs are rich in energy and provide fuel to the cells to perform functions.
