Why do runners consume glucose?
In order to run or even live you need for your body to create energy in the form of ATP (adenosine tri-phosphate) by a process called cell respiration. Glucose is needed in this process. We get our glucose through the foods we eat (glucose=sugar).
How do the cells in the human body get and use energy?
This one reason why we need to eat. The cells use a simple sugar called glucose to produce a macromolecule: ATP. It requires a large number of steps to get from a hamburger bun to glucose and ATP, but ATP holds the energy that the cell requires from moving muscles to running the nervous system.
What condition causes insulin to be released by beta cells?
The condition that causes insulin to be released by beta cells is a high level of glucose in the blood. When blood glucose levels rise after a meal, beta cells in the pancreas detect this increase and secrete insulin to help regulate glucose levels by allowing cells to absorb and use glucose for energy.
What helps your cells be able to eat the sugar needed for energy called?
Well, they don't exactly 'eat' it. Glucose (sugar used in cells) diffuses into the cells from blood plasma, aided by insulin. Once inside the cell, glucose moves to the mitochondria of the cell where cellular respiration (Krebs cycle) breaks the glucose down by the use of an electron transport chain, and the chemical energy released when the C-H bonds are broken in the glucose to form CO2 and H2O is stored in ATP molecules by a process called active phosporylation. It is a complex cycle, but the summary is: Glucose (C6H12O6) molecules are broken apart to form wastes, CO2 and H2O. The C-H bonds in the glucose are rich in chemical energy, and the purpose of breaking the glucose down is to release that chemical energy and use it to add phosphate ions to AMP (adenosine monophosphate), making first ADP(adenosine diphosphate) and then ATP (adenosine triphosphate). ATP molecules hold the chemical energy in the bonds of the 2 phosphate ions that have been added to them in this process, and the cell can 'spend' that energy for metabolic reactions in the cell by breaking off the two phosphates, releasing that chemical energy into the reactions.
What is considered to be the power-house of the cell?
The powerhouse of the cells is known as mitochondria, an organelle that is involved in the ATP-producing process. ATP is the source of energy for your whole body, and therefore your cells contain mitochondria to essentially power the cell.
What does a mitochondrion do with glucose?
Glucose is the fuel for the cell but it has to broken down first. In the mitochondria, it goes through steps which break it down a bit at a time and this process makes ATP. ATP is the energy coin of the cell which it then spends to do its' work.

Which molecule ATP or glucose stores more energy?
A glucose molecule can store much more energy than a molecule of ATP. Through cellular respiration, the energy stored in glucose is transferred to ATP molecules. ATP molecules then travel to the locations in the cell that need the energy.
How does a cell get glucose?
By the food we eat.
How are ATP and glucose similar?
ATP and glucose are similar because they are both chemical sources of energy used by cells. They are very different in terms of composition and structure. Glucose is made up of carbon, hydrogen and oxygen only whereas ATP has phosphorus and nitrogen in addition to the aforementioned three elements. Also, glucose is different from ATP in that the glucose does not have an aromatic ring even if it has a six membered cyclic ring.

The energy available for use by the cell is obtained from the life function?
Many cells typically obtain their energy through sunlight or organic molecules which help the cell undergo specific energy pathways which turn these sources into energy in the form of ATP or NADH. (Tried keeping it as simple as I could)
What does the mitochondrion do for a cell?
Most of the adenosine triphosphate, ATP, is synthesized in the mitochondria from the food we eat by the process of oxidative phosphorylation. ATP is the energy currency of the cell, the currency " spent " on cellular work.

Is mitochondria an organelle that burns a cell's food for energy?
Kind of. But it does a lot more than burn it. If we just burnt food we would get a big release of energy instantly. Instead mitochondria produce a chemical called ATP which we use for energy. Each molecule of glucose you eat produces 36 molecules of ATP.
