What is the smallest subunit into which starch can be broken down? - Glucose (monosaccharide). During digestion, the chief cells of the stomach secrete _____________ , which is responsible for the digestion of protein. - pepsin Circle the correct underlined term: The liver / stomach produces pepsin which, in the presence of hydrochloric acid, digests protein. - stomach ________________ is a hydrolytic enzyme that breaks starch down to maltose. - Salivary amylase A ________________ is made...

The neurotransmitter released into the synaptic gap reaches the target cell by - diffusion You have just observed that each action potential in a burst can trigger additional neurotransmitter release. If calcium ions are removed from the extracellular solution, what will happen to neurotransmitter release at the axon terminal? - there will be more neurotransmitter release The end of the axon where it contacts a target is called the - axon terminal Neurotransmitter is released into the synap...

What is the key variable in an isometric contraction of a skeletal muscle? - The length-tension relationship. Based on the unique arrangement of myosin and actin in skeletal muscle sarcomeres, explain why active force varies with changes in the muscle's resting length. - When the skeletal muscles resting length increases, there is more time for myosin bridges to return to their starting position. Note the dip in total force at a muscle length of 90 mm as compared to the total force at a mu...
