Bio exam 3

Fermentation pathways

does not use free oxygen, fewer energy is produced compared to pathways that uses oxygen. This pathway only partially breaks apart food molecules

Aerobic cellular respiration

this pathway requires the use of free oxygen and fully breaks apart food molecules in return much more energy is produced from this pathway. More effective by 18x

substrate level phosphorylation

adding a phosphate to molecule from atp to release molecule with Pi +ADP

co enzymes

molecules that aid in the proper function of other enzymes

Glycosis

In the cytosol; glucose (6e)- Split into 2 carbon pyruvate molecules + 4 ATP molecules + 2 NADH

Prekrebs/Krebs cycle

matrix of mitochondria; 2 pyruvates are oxidized in 6 Co2, generate 2 atp, 8 NADH, 2 FADH2

elecctron transport system

inner mitochondrial membrane; oxidative phosphorylation, 34 ATP

chemiosis-

using an h gradient to do work

Alcohol fermentation

starts with glycosis, cuts off 2 co2 and produces acetaldehyde, then produces ethanol

lactaid fermentation

starts w glycosis, cannot go into mitochondria (No O2) the pyruvates are gonna turn into 3 carbon molecules called lactate

anabolic pathways

metabolic pathways that require energy to build complex molecules from simpler starting materials
