Chapter 15 Signal Transduction 1) Endocrine‚ paracrine ‚ autocrine signaling‚ and cell-cell contact (Fig. 15-2). Endocrine signaling is long distance signaling. An example would be pancreatic cells secreting insulin. Paracrine signaling is for close proximity. An example would be a nerve cell releasing neurotransmitters. In autocrine signaling the cell that produces the ligand also contains the receptor for that ligand. This is how cancer cells work. In signaling by plasma membrane attached
Premium Protein Cell membrane Signal transduction
G-protein Coupled Receptors (GPCRs) are cell surface proteins that relay extracellular signals to the nucleus. These signals can be in the form of light‚ peptides‚ lipids‚ and sugars. Once activated by a ligand at the outer cell surface‚ GPCRs activate their cognate G-proteins that reside on the inner cell membrane. The activated G-proteins then slide along the inside of the cell membrane to activate a cascade of proteins and enzymes that in turn amplify the original message received by the GPCR

The mTOR Pathway Introduction The mammalian target of rapamycin (mTOR) signaling pathway integrates both intracellular and extracellular signals and serves as a central regulator of cell metabolism‚ growth‚ proliferation and survival. Discoveries that have been made over the last decade show that the mTOR pathway is activated during various cellular processes (e.g. tumor formation‚ insulin resistance‚ adipogenesis and T-lymphocyte activation) and is deregulated in human diseases such as cancer

DIFFUSION REVIEW WORKSHEET 1. Define diffusion and what causes it to occur? The action of spreading the light from a light source evenly so as to reduce glare and harsh shadows. Diffusion is caused when entities are small and moving in molecules. They collide because they are moving at a random pace. The temperature causes diffusion. 2. Define the terms hypertonic‚ hypotonic‚ and isotonic solution. * Hypertonic: Having increased pressure or tone‚ in particular. * Hypotonic:

Physiology Linder Unit 1 Possible Essay Questions Chapter 1 1. Describe the concept of homeostasis. Explain how negative feedback and positive feedback loops effect the homeostatic condition. Use examples to explain your answer. Homeostasis can be described as maintaining a relatively internal environment even though the external environment is variable. Negative feedback loops effect the homeostatic condition by controlling it by bringing you back to your set point

Introduction First discovered as the major signal transducer in interferon-mediated gene activation‚ STATs (signal transducers and activators of transcription) are now known to play a significant role in signal transduction for most cytokines. STATs represent a family of conserved proteins‚ seven of which have been identified in mammals (i.e.‚ Statl‚ 2‚ 3 ‚ 4 ‚ Say5b‚ and 6;
