Which type of muscle cell propels substances or objects through internal passageways? skeletal. cardiac. smooth. striated.

Smooth muscle

Explanation:

The smooth muscle is present in the hollow organs and propels the substances through these hollow internal passages like in the alimentary canal of the digestive tract and urinary bladder.

Thus, the Smooth muscle is correct.

both anaerobic and aerobic respiration use glucose (or other carbohydrates), proteins and lipids to produce atp and nadh. cell uses those energy molecules, obtained from food and   breaks them down during the chemical reactions of respiration. in anaerobic respiration, nadh is regenerated to nad+ by enzymes lactate dehydrogenase (lactate is produced, e.g. in muscle cells) or by alcohol dehydrogenase where ethanol is produced (alcohol fermentation), while in aerobic respiration, electrons from nadh are deposited in the mitochondria to regenerate nad+ (electron transport chain. anaerobic respiration produces 2 atp per molecule of glucose compared to aerobic respiration where about 38 atp molecules are produced.
