  • Describe endocrine, paracrine, and autocrine signaling. correct answers Endocrine: An endocrine cell releases a hormone into the blood stream to target a receptor on the target cell. Paracrine: A signaling cell releases a local mediator to target cells (neighboring cells). Autocrine: A cell releases a chemical signal to target itself. How does a hormone that is released generally throughout the body end up having different effects on (or no effects on) different cells? correct answers H...

  • Why are there motor proteins associated with both actin filaments and microtubules but not intermediate filaments? - Answer Actin filaments and microtubules are highly polarized, therefore allowing motor proteins to form associations with them. Intermediate filaments are unpolarized and do not bind nucleotides such as ATP, leading to lack of motor protein associations (which are ATP driven). How does the hydrolysis of ATP cause myosin to move along the actin filament? - Answer ATP hydroly...
