∙ 8y agoThis is a very general question, but I'll give it an attempt. Glucose is oxidized via glycolysis to produce reduced coenzymes (2 NADH) and ATP. The product of glycolysis (pyruvate) then enters the citric acid cycle and is further oxidized to produce more reduced coenzymes (3 NADH and 1FADH2) and GTP (a high energy phosphate equivalent to ATP). The reduced coenzymes (NADH, FADH2) enter the electron transport chain and then are oxidized to release electrons. The electrons traverse the electron transport chain via several electron transport molecules and ultimately reduce oxygen to form metabolic water.

∙ 14y agoGlucose--but the wording of the question is misleading--the sugar itself does not combine with oxygen. Rather, as glucose is broken down into smaller compounds, electrons ("reducing equivalents") are released which eventually pass down what amounts to a stepwise gradient of energy, called the electron transport chain (ETC)--as they pass along this gradient, some of that energy is dissipated as heat and thus lost, but another bit of it is saved in a chemical form (so-called ATP) that is usable to the cell. At the end of the chain, the electrons themselves combine with oxygen to produce water. The other major product of this whole process is carbon dioxide, released at several points prior to the electrons entering the ETC.

∙ 11y agoMy Science textbook says "Your cells use oxygen to break down sugar into carbon dioxide and water. When your cells break sugar down, they release energy from the sugar."
Does that answer your question?

Oxygen is important cells as without oxygen the human body is unable to release enough energy to support life. In theory any other element in the oxygen-group on the Periodic Table can be used to release energy but because other elements in that group are not easily turned into gases they can't used. Last comment; Oxygen is not important for blood; its important for the blood cells themselves and other cells. Blood and blood cells are very different.
do the math
Contrary to popular secular belief, tree's don't actually produce the majority of the worlds oxygen, in fact, approximately 91.6% of the worlds oxygen is produced by phytoplankton blooms in the northern hemisphere of the ocean.
protein
Yes - oxygen is held in red blood cells (in haemoglobin to be precise). As the blood flows, oxygen is brought all around the body and eventually gets back to the heart and lungs as carbon dioxide (which is what you exhale).
Oxygen is requried for respiration (your cells making 'energy'.)

Cellular respiration is the process by which cells produce energy (in the form of ATP) from food (glucose) in the presence of oxygen.
