Which bond must break in ATP for energy to be released?
The high energy phosphate bond. This bond is broken by the enzyme ATPase.
What does a mitochondria use to make energy?
The mitochondria has 3 proton pumps (intramembranous proteins) situated in the inner membrane of the mitochondria. This membrane is between the matrix and the intermembranous space. By the help of electrons passing through the pumps, donated by NADH and FADH2, protons can be pumped to the interstitial space of the two membranes. This will increase the electrochemical gradient of protons between that space and the matrix. This electrochemical gradient created, will force protons to pass through an additional protein called ATPase. This ATPase will procure the kinetic energy produced by the movement of protons through its channel and use it to make ATP. ATP is a high energy molecule used by the body later as "batteries". In other words the Mitochondria doesn't release energy, it packages it for the rest of the body.
How does the electron transport chain during muscle exercises work?
when NADH and FADH is oxidized from the matrix of the mitochondria of the muscle cells h+ protons pass through proteins on the inner membrane of the mitochondria. the proton gradient made by this cause protons to come back down into the mitochondrial matrix by passing through a atpase that generates ATP(energy from adp) by using the work from the proton gradient. the ATP newly made by this atpase is the energy that the cells use for muscle activity.
How does and electron transport chain result in the gradual release of energy stored in glucose?
Basically NADH and FADH are oxidized to by oxidizing agents in the ETC. Since the electrons are moving from something less electronegative to something more electronegative, free energy in released. This free energy takes H protons and moves it against the inner membrane to the outside. Eventually, the outside will create a concentration gradient, and cause the H protons to pass through a area on the membrane called ATPase. As the H protons move through ATPase, ADP is turned into ATP. This processes doesn't happen all at once, but happens over time from the NADH and FADH glucose creates during glycolosis and the citric cycle. These NADH and FADH are oxidized "slowly", so energy is gradually released to create ATP.
What does ATP used for in the body 3 primary functions?
ATP is the energy currency of the cell (or the fuel). The energy is store in the high energy phosphate bonds.The 3 primary functions of ATP are1) maintenance of the Na/K pump (Sodium-potassium pump or ATPase)2) production of mechanical energy in the contraction and relaxation of muscle3) action potential signalling
What is the membrane ATPase and what does it do?
ATPase Is an enzyme that works in and around the membrane to break down ATP (Energy Made By The Mitochondria) into ADP
Where is ATPase enzyme needed for muscle contraction located?
It is in the mitochodria and speeds up the formation of ATP by breaking down ATP into ADP + energy. Muscle cells have many more mitochrondia than other cells.

What is the role of myosin APT ase in muscle contraction?
Myosin ATPase hydrolyze ATP into ADP+pi and yielding the energy required for muscle contraction.
What us active transport?
Considering that active transport is the movement of a solute across a biological membrane such that the movement is directed upward in a concentration gradient (i.e., against the gradient) and requires the expenditure of energy. Acrtive transport is an endergonic process that is often coupled to the hydrolisis of ATP. Three types of ATP hydrolizing, transmembrane proteins or "pumps" are known that actively transport cations: a) P-type ATPases, located mostly in plasma membranes; b) F-type ATPases (F1F0), located in mitochondria; and c) V-type ATPases, located in plant vacuolar membranes and acidic vesicle, such as animal lysosomes.The most known active transport pumps are: (Na+-K+)-ATPase of plasma membrane, Ca2+-ATPase , and (H+-K+)-ATPase of gastric mucosa.Finally, the most known ions that use active transport are Na+, K+, and Ca2+.

Where is the energy stored in an ATP molecule and how is it released?
ATP is a molecule with 3 phosphorus groups. The 3rd phosphorus group has a high energy bond connecting it to the 1st 2. When energy is needed by the cell to do work this 3rd bond is broken.

What is the energy located in the bonds of food molecules?
The location of energy release from food molecules is in the mitochondria of the cell. The process in which energy is released from food molecules is known as cellular respiration.
