Respiration vocabulary

1. Cellular Respiration –

Energy stored in food is released. It happens inside cell.

2. ATP – Compound in which energy released by cellular respiration is stored

3. ADP – Lower energy compound remaining after one phosphate group is removed from ATP. LESS ENERGY THAN ATP

4. Adenosine – Adenine and ribose

5. Oxidation – Any change in which an atom of molecule loses electrons

6. Reduction – Reducing the charge-more negative. Gaining electrons

7. Aerobic Respiration –

Respiration requiring the presence of free oxygen; glucose is oxidized so maximum energy is removed from glucose

8. Anaerobic Respiration –

Respiration in the absence of free oxygen; glucose is partially oxidized so little chemical energy is removed from glucose

9. Steps of Aerobic Respiration –

1. Glycolysis; (rest of steps happen in Mitochondria) 2. pyruvic acid breaks down into CO2, NADH, and a 2-carbon

compound combined with coenzyme A to form acetyl CoA

10. Steps of Anaerobic Respiration –

1. Glycolosis (break down of glucose into two 3 carbon pyruvic acids molecule). (happens in cytoplasm);

2. fermentation (conversion of pyruvic acid no additional ATP is produced)

11. Glycolysis –

break down of glucose into two 3 carbon pyruvic acids molecule

12. Fermentation –

conversion of pyruvic acid no additional ATP is produced

13. Krebs Cycle –

Provides 4 pairs of electrons; 1 ATP is produced by each turn of the cycle;

14. Electron System of enzymes and coenzymes located in mitochondrial membrane. Series of oxidation-reduction reactions take place; electrons are carried

Respiration vocabulary

Transport Chain –

by NADH and FADH2. Electrons give up energy and ATP is formed; water molecules are formed; total of 32 APT molecules for each molecule of glucose

15. Equation for Respiration –

6O2 + C6H12O6 6H2O + 6CO2 +36 ATPOxygen + Glucose Water + Carbon Dioxide +Energy

16. Equation for Photosynthesis –

6CO2 + 6H2O C6H12O6 + 6O2Carbon Dioxide + Water Glucose + Oxygen
