——-ability of muscle cell/fiber to respond to stimulation by nerves and hormone

Skeletal muscles Largest organ in body ____of total body mass

A tough, sheet-like structure made of fibrous connective tissue
Attaches muscles to other muscles

Dense Connective tissue divides a muscle into sections called fascicles

Myofibrils:
Thick and thin Myofilaments
Contractile protein of muscle Separated by SR

covers myosin-bindings sites on actin filament

Why do muscle cells use myoglobin not hemoglobin?

Functional unit responsible for muscle contraction

Have less mitochondria

dense with capillaries

fast isoforms of contractile proteins

Strap-like

(it is the most powerful
muscle)

is a prime mover of extension of the elbow joint.

Insulin is not required for the uptake of glucose by intestinal cells.

All three monosaccharides are transported from the intestinal mucosal cell into the portal circulation by the transporter

Fructose uptake requires a sodium-independent monosaccharide transporter

The transport of glucose and galactose across the brushborder membrane of mucosal cells occurs by
