Question 5

Match the bands, labelled a. through c., with the descriptions. (Options may be used more than once or not at all.)
a.A band
b.I band
c.H zone
-composed of thick and thin filaments

Accepted Answer

The A band is the region in a sarcomere where thick and thin filaments overlap, and it is composed of both types of filaments, making it the correct match for the description.

Question 6

Match the bands, labelled a. through c., with the descriptions. (Options may be used more than once or not at all.)
a.A band
b.I band
c.H zone
-composed of thin filaments only

Accepted Answer

The I band in muscle fibers is composed of thin filaments only, which are primarily actin filaments. This contrasts with the A band, which contains both thick (myosin) and thin filaments, and the H zone, which contains thick filaments only.

Accepted Answer

Slow-oxidative fibres can be transformed into fast-oxidative or fast-glycolytic fibres by specific training, whereas the other two fibre types cannot be transformed.

Question 14

Match the muscle fibre types, labelled a. through c., with the characteristics. (Options may be used more than once or not at all.)
a.slow-oxidative fibre
b.fast-oxidative fibre
c.fast-glycolytic fibre
-most resistant to fatigue

Accepted Answer

Slow-oxidative fibres are the most resistant to fatigue due to their ability to use oxidative metabolism, which produces energy at a slow rate but with a high yield of ATP, allowing for sustained activity without fatigue. Fast-oxidative fibres also use oxidative metabolism but do not have as high of a resistance to fatigue. Fast-glycolytic fibres use anaerobic metabolism, which produces energy quickly but with a low yield of ATP, causing fatigue to set in quickly.
