AP Biology Questions and Answers (Graded A) Resting membrane potential depends on which of the following(s)? I. Active transport II. Selective permeability III. Differential distribution of ions across the anxonal membrane All three. The resting potential depends on active transport (the Na+K+ATPase pump) and the selective permeability of the axon membrane to K+ than to Na+, which leads to a differential distribution of ions across the axonal membrane Mitosis The division of the moth...

Endocrine Anatomy and Physiology Analyze the anatomy and physiology of the endocrine system: 1. Examine the production and action of hormones produced by the thyroid, pancreas, and adrenal glands. • Thyroid: ▪ T4 (90%): 1. Released by thyroid gland  converted to T3 inside of cell prior to entering nucleus ▪ T3 (10%): 1. more potent, actions are short-lived, present in blood in much smaller amounts than T4 2. stimulates production of the contractile protein a-myosin heavy chain i...
