Term
|
Definition

|
|
Term
|
Definition
| tells what a particular value should be (includes set point) |
|
|
Term
|
Definition
| elicit responses that change conditions in the internal environment |
|
|
Term
|
Definition
| Stimulus (body temp. rises above normal)--Receptors (Thermoreceptors send signals to the control center)--Control center (the hypothalamus detects the deviation from the set point and signals effector organs-- Effectors (skin blood vessels dilate and sweat glands secrete)-- Response (Body heat is lost to surrounding. temp. drops toward control |
|
|
Term
|
Definition
| Different from when too when the temp continues to drop the muscles start to contract involuntary--which then generates body heat. |

|
|
Term
|
Definition
-lipid bilayer
-contains lipids, carbohydrates, proteins |
|
|
Term
|
Definition
forms the bilayer allowing materials to flow through membranes
-rigid to support the membrane |
|
|
Term
Proteins:
-Integral
-Peripheral |
|
Definition
1. "whole"--works as a channel
2. Cell recognition-works as channel but not allowing things all the way through. projects from outer surface |
|
|
Term
|
Definition
| glycocalyx: important in cell recognition |
|
|
Term

perinuclear space
nuclear pores
nucleolus |
|
|
Term
|
Definition
Endoplasmic Reticulum
Ribosomes
Golgi Apparatus
Mitchondria
Lysosomes
Microtubules & Microfilaments |
|
|
Term
|
Definition
-agranular
-continuous w/ rER
1. lipid synthesis--steroid hormones
2. detoxification of drugs and alcohol
3.glycogen metabolism; has enzyme that breaks down glycogen into glucose
-No ribosomes |
|
|
Term
|
Definition
-granular
-membranes channels--cisternae
-ribosomes attach(stud) the surface giving it a ROUGH appearance
-responsible for synthesizing lysosomal and secretory proteins |
|
|
Term
|
Definition
1. attached to outer surface of membranous structures (synthesize secretory protein)
2. free in the cytoplasm (synthesize cytoplasmic proteins)
|
|
|
Term
|
Definition
| -joined my mRNA--provides the genetic code instructing ribosomes on how to put the protein together |
|
|
Term
Golgi Apparatus (mail center--gets stamped and sent on its way)
what is the step system? |
|
Definition
| In network of nucleus, as a series of fattened sac. Functions in modification & packaging of proteins & forms lysosomes--directs macromolecular traffic throughout the cell--responsible for recycling membrane between the rER and cell membrane |
|
|
Term
|
Definition
| prokaryote which established a symbiotic relationship in host cell--replication system--Therefore cells that use a lot of energy have lots of mitochondria |
|
|
