Answer;
-Protein ions
A resting axon's fluid interior has a mostly negative charge thanks to the presence of large protein ions.
Explanation;
-Intracellular and extracellular fluid of neurons contain various kinds of charged ions. These include sodium (Na+), potassium (K+), and chloride (Cl-). Additionally, these fluids contain many negatively charged protein molecules called anions (A-).
-The movement of such ions across neural membranes creates electrical activity. As ions move in and out of the cell, they bring their respective charges (either positive or negative) with them, thus influencing the voltage of cellular membranes.
-The protein molecules are large negatively charged proteins (anions) that are manufactured inside cells. They always remain inside the cell, as there are not membrane channels through which they can leave.Their charge contributes to the negative charge on the intracellular side of the membrane.
Answer:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function. Energy is stored in the bonds of glucose (like a stretched rubber band), and when glucose is broken down, much of that energy is released. Some of it is captured in a form that can be used to do work in cells - a molecule called adenosine triphosphate or ATP. The energy that is not captured in ATP is usually given off as heat (one of the things that helps us maintain our normal body temperature).
