Document Summary
The metabolic process that happens to the food that we eat. The food was oxidized and the products are reducing equivalents or reduced products: nadh & fadh2. These are reduced because they have h atoms. Needs to be further converted to energy (oxidized) etc. Plants provide us with oxygen in order to use the food that we eat under aerobic metabolism. Oxygen is reduced to water with production of a lot of atp. Atp can be used by energy-requiring processes. Cleave atp and release adp and inorganic phosphate. Adp and inorganic phosphate are used again for the oxidative process. It depends or resides on these different concepts: all organisms are open systems, all organisms exist in a steady state. Living organisms are essentially isothermal: once open, they can readily exchange matter and energy with the environment. Rate of transfer in and out of the system is constant. Something released, there should also be something absorbed.
