Lipid derived hormones Study guides, Class notes & Summaries

What is a hormone and how does it act? Hormones are chemical messengers that are responsible for regulation. They are secreted into body fluids, mainly blood. It has specific actions on target tissues, which are any tissue that has specific receptors for that particular hormone. Understand the role of negative feedback in control of hormone secretions. A control mechanism in which rising level of a hormone leads to a decrease in hormone secretion What is a paracrine secretion? g...

1. Glucose typically enters the cell through which mechanism? A. Simple diffusion through the cell membrane B. Facilitated diffusion through a carrier protein C. Pinocytosis through a channel protein D. Active transport by a glucose transport protein - AnsFacilitated diffusion through a carrier protein Glucose is too large and polar to move quickly through the cell membrane by simple diffusion. Typically, the concentration of glucose outside the cell is higher than inside the cell. Sinc...
