anaerobic respiration Flashcards

1
Q

describe the process of glycosis

A

glucose goes to phospholyated glucose (2ATP–> 2ADP)
phosphorlyated glucose goes to GP (3C)
GP goes to pyurvate (4ADP –> 4ATP) (2NAD+ –> 2NADH)

Q

compare the structure of lactate and pyurvate and explain what happens to pyurvate (3)

A

lactate and pyruvate both have 3c
pyruvate has hydrgoen added to it to form lactate so it has been reduced
reduced coenzyme is required for the converstion

Q

explain the production of lactate in muscle cells

A

lactate is produced during anaerobic respiration
glucose is converted into pyurvate
pyurvate is then converted into lactate
as there is no oxygen to be the final electron acceptor in the ETC the krebs cycle and oxidative phosphorlyation cannot take place
lactate diffuses into the blood and transported to the liver

Q

describe the role of the liver

A

liver removes lactate as it is converted into pyurvate through oxidation
NAD is reduced and pyruvate enters the kreb cycle
complete oxidation of glucose can now ccur
LDH is required for the conversion of lactate

Q

explain why a reduced production of ATP would lead to cramps (3)

A

there is less ATP to bind to myosin heads
myosin is unable to detach from actin
actomyosin cross bridge doesnt break
muscles remain contracted
