Answer:
K+
Explanation:
Leak channels are the gated channels that randomly open and close. The plasma membranes have many more potassium ion (K+) leak channels than the leak channels for other ions such as sodium ion. Also, the potassium ion leak channels are leakier than the sodium leak channels and allow exit of more and more K+ from the neurons. This makes the inside the neuron negative at rest and outside becomes more positive. In this way, the leakage of K+ across the K+ leak channels is mainly responsible for maintaining the resting potential.
Answer:
Providing energy and regulation of blood glucose.
Sparing the use of proteins for energy.
Breakdown of fatty acids and preventing ketosis.
Explanation:
The main function of carbohydrates is to provide energy and regulation of glucose in the blood. It prevent the use of proteins for production of energy and also promote breakdown of fatty acids and preventing ketosis. Ketosis is a process that occurs when our body doesn't have carbohydrates in sufficient quantity for the production of energy. Carbohydrates are the first biomolecules that are used for energy production.
