28
Q

What releases the Ca ions in teh mcueles?

A

the spread of action potential in the muscles leads to teh release fo Ca++ from the sarcoplasmic reticulum

29
Q

What leads to the unmaksing of the active binding sites in the muslces?

A

bindng of Ca++ to the tropnonin which uncovers the binding sites of the actin and thus leading to myosin binding to it

30
Q

Where are the Ca++ pumped back into ?

A

they are pumpoed back into the sarcoplasmic reticulum

31
Q

What leads to fatigue?

A

repeated activation leads to the accumulation of lactic acid int eh muscles which leads to fatigue

32
Q

What leads to accumulation of lactic acid in the muscles?

A

due to the anaerobic breakdown of glycogen in the msucles

33
Q

What is the concentration of myoglobin the red and white muscles fibres?

A

red muscles had more myoglobin

34
Q

Which muslces has more number of saroplasmic reticulum?

A

white fibres have more sarcoplasmic reticulum than red

35
Q

Which muslces has more number of mitocondria ?

A

white has more mitochondria than red

36
Q

Which depends on anaerobic reticulum for energy?

A

white fibres have anaerobic respiration for energy

37
