Question

2. Regarding energy usage (0.5pt each); a. What process would give you a few more seconds worth of ATP while you wait for your cardiovascular and respiratory systems to increase your oxygen supply? b. Which process involves mitochondria using glucose and oxygen to produce lots of ATP? c. In which process do muscle cells use glucose without oxygen to produce ATP? d. Which process accounts for most of the ATP production in muscles?

Answer 1

2.a) Creatine phosphate metabolism will provide few more seconds worth of ATP. During rest stage ATP gives its phosphate to creatine and makes creatine phosphate.During contraction the creatine phosphate transfers its phosphate to ADP and make ATP. This creatine phosphate derived ATP will provide energy for few seconds.

b) The process is Aerobic respiration.It involved Glycolysis+Link reaction+Electron transport Chain. It provides 32 ATPs per glucose molecule.(as per new norms, previously it was 34 ATPs per Glucose molecule)

c) Anaerobic Glycolysis. It produces less ATP and Lati Acid.

d)Aerobic respiration
