- Production of ATP
- creates CO2 and water, efficient needs O2
- transferring phosphate from organic molecules to ADP
- creates ATP by Substrate-Level Phosphorylation
- energy from H+ ions being pumped across the gradient
- Chemiosmosis-makes ATP
- Redox Reactions
- NADH delivers e- to e- in transport chains, releases smal amounts of energy
- Steps of Respiration (location)
- 1)cytoplasm 2-3) mitochondria
- 3 Stages of Cellular Respiration
- Glycolosis, Krebs Cycle, Electron transport
- Glycolysis
- glucose oxidated to pyruvate, ten step process, glucose activated by ATP & add of P, Energy harvest =NADH and ATP
- Products of Glycolysis
- Pyruvate-(2/glucose) ATP-(2/glucose) NADH-(2/glucose
- transition from Glycolysis to Krebs Cycle
- each pyruvic acid molecule broken down to make CO2 and 2carbon acetyl group enter the cycle
- Kreb's Cycle
- 2 carbons combine with 4 carbons, spin, --6 NADH and 2 FADH
