cellular respiration

aerobic respiration

oxygen is needed to produce energy,

occurs in body cells in mitochondria (some have more mitochondria than others bc some are more metabolically active, ex. skin cells vs muscle cells)

anaerobic cellular respiration

no oxygen is needed to produce energy, usually from workouts where the muscles get tired

muscle cramps

lactic acid build up in cytoplasm, some die, which lead to the rebuilding of new and better cells

AR glycolisis

happens in cytoplasm

sugar is split, breaking down of glucose to make pyruvate

uses 2 ATP

MAKES: pyruvate, 2 ATP and 2 NADH

reduction

gaining of electron causes charge to change

NAD+ → NADH, positive charge is neutralized by electron and turns into H

KREBS cycle

occurs in mitochondria

pyruvate & NADH enters thru electrotransfer

produces NADH, FADH2, CO2, ATP

electro transport chain

happens in inner membrane mitochondria

where 32 ATP is produced

oxygen is needed, water is a byproduct

acidity

measures how many protons are in a fluid

chemiosmosis

movement of ions down the electrochemical gradient, leads to ATP production

AN gylcolisis

NADH makes pyruvate, but no oxygen so NADH becomes NAD+

only creates 2 instead of 32 ATP, leads to cell death

lactic acid fermentation
