Cellular respiration

Chemical reactions that take place in the body to create energy from nutrients that have been consumed

breaks down larger molecules into smaller molecules to release energy into cells to carry out required life processes

builds larger molecules from smaller ones and consume energy. cells use energy to perform anabolic reactions

• sends energy to carry out anabolic reactions • temporary energy storage that’s been transferred from high energy catabolic reactions • Releases the energy when the cell requires it • high energy phosphate bonds store energy

requires oxygen and creates 32 ATP total through citric acid cycle and electron transport chain

Glycolysis occurs in the cytosol and has 2 ADP and glucose to start with and ends up with 2 ATP and 2 pyruvic acid (half glucose molecule)

occurs in the mitochondrion and you start with the pyruvic acid and 2 ADP and end up with 2 ATP and CO2

also occurs in mitochondrion and starts with oxygen and 28 ADP and end up with 28 ATP and H2O

does not require oxygen same as glycolysis but end result is 2 ATP and lactic acid (can be recycled)
