What are the major glands of the endocrine system? - Answer-Hypothalamus, Pituitary gland, thyroid gland, parathyroid gland, pancreas, adrenal cortex, gonads(ovaries and testes). Tropic Hormones? - Answer-Hormones that that regulate the secretion of another hormone. ex-the hypothalamus secretes tropic hormones that regulate the anterior pituitary gland. Hormone definition? - Answer-A hormone is a chemical produced by a group of specialized cells that are released into the blood in minute qu...

Lesson 1: Foundations to Set the Stage - Correct answerFocusing on Cellular Structure and Function - Correct answerThe Normal Cell Cycle - Correct answer--The cell cycle refers to the ordered seres of processes of DNA replication and mitosis, or cell division -Cell nucleus regulates these processes by gathering and processing complexes molecular information Interphase and Mitotic Phase - Correct answer-Cell division produces two identical cells through these two major phases During interph...

Biol 1201 Final – Gregg Latest Update Graded A+ local signaling animal cells may communicate by direct contact, or cell-cell recognition (paracrine and synaptic signaling) cell junctions Animal and plant cells; directly connect the cytoplasm of adjacent cells paracrine signaling the target cells lie near the secreting cells synaptic signaling a nerve cell releases neurotransmitter molecules into a synapse, stimulating the target cell endocrine (hormonal) signaling Specializ...

Which of the following signaling types occurs during periods of development specifically for the secretion of growth factors? paracrine signaling Explain why a steroid hormone would require a carrier protein to transport it through the bloodstream. Steroid hormones are hydrophobic so they would need a carrier protein to carry it through the blood because carriers are hydrophilic Explain what a ligand is and give an example of one. A ligand is a molecule that has specificity for a given rece...

What are the 5 well-known enzyme-linked cell surface receptors? - ANSWER 1. Receptor Guanylyl Cyclase: produces cGMP 2. RTK: phosphorylate tyrosine residues leading to association of signalling molecules and cascade 3. TK Associated Receptors: associate with proteins having TK activity 4. Receptor Tyrosine Phosphates: Removes phosphate on tyrosine residues 5. Receptor Serine/Threonine Kinases: phosphorylate specific Serine/Threonine residues on IC signalling molecules How are RTK and TK...
