O2 is the final acceptor in the electron transport chain.
It is the final electron receptor in the process of cellular respiration.
Oxygen is used for oxidation of organic compounds to release energy
cellular respiration helps us and other animals get energy from our food and oxygen and water. photosynthesis lets plants, algae and bacteria get energy from light energy and carbon dioxide
Mito, short for mitochondria, is responsible for energy production in cells through cellular respiration. It generates adenosine triphosphate (ATP), the molecule that supplies energy for various cellular processes. Additionally, mitochondria play a role in regulating cell metabolism, calcium signaling, and apoptosis (programmed cell death).
awesome stuff
Active transport is moving substance against its gradient so it requires an input of energy to achieve this. One example is Na K ATPase. This is a secondary active transporter that pumps 3x Na out of the cell for 2x K into the cell. There are so much more Na outside the cell and already a lot of K inside the cell so to push the molecules there is an expenditure of ATP to do this.
active transport is kind of like diffusion, but unlike diffusion, it requires ATP(energy) and the molecule moves from low concentration to high concentration

Active transport is the name given to the process of using energy to move substances into cells against what would happen without the expending of energy. Think of an island you want to visit. It is too far away to have a bridge so t is required to expend more energy than usual to get there--either by boat or plane, for example. Osmosis or diffusion account for movement of substance within another substance or across a membrane. It could be argued that there is energy involved in these movements, but no ATP is used. Active transport requires either ATP or electrochemical potential for movement. Sometimes, active transport moves substances against a concentration gradient. In the case of roots, the concentration of "fertilizer" or ions in the soil may be far less than in the tissues of the roots, yet active transport allows more ions to enter the roots. This is the method of obtaining glucose, for example, from your intestinal contents in the cells of the intestine. Active transport is like a ferry, but you have to pay the ferryman to gain passage.
They act as barriers to the diffusion of certain substances.Read more: What_role_does_the_cellular_membrane_play_in_passive_transport

Think of Active Transport!! Protein grabs molecule Protein rotates round Protein releases molecule Protein rotates round again But this requires energy, so alot of mitochondria are required, and also active transport goes against the concentration gradient.

it delivers oxygen

hahahah That's not even an answer. They act as barriers to the diffusion of certain substances. ---------------------------------------------------------------------------------- Better Answer: Well actually the membrane can facilitate diffusion (such as that of larger macromolecules) through channel proteins.
