**Question 3**Compared to the muscle fiber type that readily fatigues, fatigue-resistant muscle fibers:- Have fewer mitochondria- None of the other answers- Contract more quickly- Contain less myoglobin**Question 4**In muscle, when calcium is moving from the sarcoplasm to the sarcoplasmic reticulum, it is moving:- Along its gradient using ion channels- Against its gradient using pumps- Against its gradient using ion channels- Along its gradient using pumps**Question 5**In the heart, blood flows from:- Artery to ventricle to atrium to vein- Artery to atrium to ventricle to vein- Vein to ventricle to atrium to artery- Vein to atrium to ventricle to artery

None of the other answers. O Contract more quickly O Contain less myoglobin ESTION 4 muscle, when calcium is moving from the sarcoplasm to the sarcoplasmic reticulum, it is moving: D along its gradient using ion channels D against its gradient using pumps against its gradient using ion channels O along its gradient using pumps JESTION 5 n the heart, blood flows from: O artery to ventricle to atrium to vein O artery to atrium to ventricle to vein O vein to ventricle to atrium to artery vein to atrium to ventricle to artery
