Question

14. During intense (heavy) exercise, the initial ability of oxidative phosphorylation to provide l muscle enough ATP for the sudden demand of increased force generation by the skeleta is IS , thereby causing the muscle fiber to quickly and massively boost its energy production from until oxygen delivery and other mechanisms come up to speed. A) enhanced : substrate-level phosphorylation B) inadequate: substrate-level phosphorylation C) enhanced: fatty acids D) enhanced: glucose E) inadequate: fatty acids 15. Which of the following is the correct order of muscle fiber recruitment, from first to last? A) slow oxidative : fast oxidative: fast glycolytic B) fast oxidative : fast glycolytic : slow oxidative )fast glycolytic : fast oxidative : slow oxidative slow oxidative : fast glycolytic: fast oxidative fast glycolytic: slow oxidative : fast oxidative 16. Where are gap junctions commonly found?

Explanation / Answer

1-during intense excercise,thr initial aniliab of oxidative phosphorylation to provide enough ATP for the sudden demand of incresedi force generation by skeleton muscle is inadequate there by causing the muscle fibres to quickly and massive boost its energy pproduction from fatty acid untill oxigen delivery and other mechanisms come upto speed.

2-its option (d) slow oxidative:fast glucolytic:fast ocidaoxid..

It is because these fibers contract in unison. Groups of motor units work together to contract an entire muscle. For one muscle to contract successfully, another muscle must relax.

So it is in that order as slow oxidative thenfast glycolytgl and then fast oxidative..

Hope u understand the answer.

Thank you
