wats the difference between glycolysis and cellular respiration?? thanks for the help

[looi_kenneth]

well, glycolysis is the foremost process of ATP generation. this process uses glucose as the initiation substance. in a successful glycolysis, 2 ATP and 2 pyruvate molecules will be generated. the pyruvates are then be transfered to the mitochondria to aid in the further process of ATP generation.glycolysis occurs in the cytoplasm while cellular respiration interacts with the extracellular environment in which the main substance that is being brought into the cell is oxygen gas, a fundamental gas for living. thank you.

A. Cellular Respiration

1. Cellular respiration includes the various metabolic pathways that break down carbohydrates and other metabolites to make ATP

2. Some processes of respiration take place under aerobic (with oxygen) and some take place under anaerobic (without oxygen) conditions

3. Overall equation for complete aerobic breakdown of glucose:

C6H12O6 + 6 O2 ----------> 6 CO2 + 6 H2O + energy

Note that respiration is the complement of photosynthesis

4. Pathways of aerobic respiration allow energy in glucose to be released slowly; ATP is produced gradually

5. Rapid breakdown of glucose would lose most energy as nonusable heat

6. Complete aerobic breakdown of glucose yields synthesis of 36 ATP; this preserves 38% of energy available in glucose



Glycolysis ("sugar splitting")

A. Occurs in the cytoplasm outside the mitochondria

B. It is an anaerobic process, universal in organisms; therefore, most likely evolved before krebs cycle and electron transport system

C. Requires an input of ATP to start

D. Glucose is broken down to two C3 molecules of pyruvate and there is a small yield of ATP (2) and NADH (2)

E. If oxygen is present the two pyruvates will move to the krebs cycle
