Muscle cells need large amounts of calcium and ATP for contraction.Based on these requirements, you would expect that muscle cells would have an increased number of what type of organelles (per unit volume)?
A) Chloroplasts and rough endoplasmic reticulum
B) Smooth endoplasmic reticulum and vesicles
C) Golgi apparatus and mitochondria
D) Peroxisomes and Golgi apparatus
E) Mitochondria and smooth endoplasmic reticulum
