BIOB34H3 Lecture Notes - Lecture 11: Oxidative Phosphorylation, Attenuation Coefficient, Partial Pressure
Document Summary
Recap: animal cells transform chemical energy from food into energy in atp bonds, which. Lecture 11 gas exchange is then transformed into other forms of energy (chemical, mechanical and heat) In the long term, animals must use oxygen as a dumping ground for the extra electrons that result from the production of atp: atp leads to the production of carbon dioxide. Newtons) per square meter others use bar (1 bar = 100 kpa), pounds per square: fy is gas (cid:494)y(cid:495) fraction of the total. Partial pressure of gas (cid:494)y(cid:495) (cid:523)py(cid:524) is calculated as: py = fyp. Partial pressure is chemical potential for gasses gasses will move spontaneously (without external energy) from areas of high potential (high partial pressure) to areas of low potential (low partial pressure) When there are multiple types of gas, we can talk about the partial pressure. When gas (cid:494)y(cid:495) is in aqueous solution the concentration cy is determined by henry(cid:495)s law.
