smooth endoplasmic reticulum definitions
# Definition Sets
1an endomembrane system where lipids are synthesized, calcium levels are regulated, and toxic substances are broken down.39 sets
2a network of membranes inside eukarytoic cells invovled in lipid synthesis (steroid in gonads), detoxification (in liver cells), and/or ca2+ storage (muscle cells).13 sets
3no ribosomes are found on surface; contains collection of enzymes that perform special tasks that include the synthesis of membrane lipids and detoxification; the liver contains a lot of smooth er12 sets
4makes molecules such as lipids10 sets
5no ribosomes, makes lipids7 sets
6endoplasmic reticulum that synthesizes lipids (oils, phospholipids and steroids), metabolizes carbohydrates, stores calcium ions that can be used to trigger a response and detoxifies drugs and poisons (usually by adding hydroxyl groups)6 sets
7the portion of the endoplasmic reticulum that lacks attached ribosomes4 sets
8makes lipids4 sets
9lacks ribosomes that populate the surface of the rough endoplasmic reticulum, diversity allows the performance of many functions3 sets
10fatty acid and steroid synthesis; detoxifies toxic substances3 sets
11called smooth because of the absence of ribosomes, has three main functions a] intracellular transport, b] lipid synthesis, c] drug and alcohol detoxification, the smooth endoplasmic reticulum is also involved in synthesizing derivatives of cholesterol such as the steroid hormones, it is especially well developed in the cells of the liver3 sets
12organelle involved with lipid synthesis and drug detoxification2 sets
13ribosomes not found on the surface. smooth er contains collections of enzymes that perform specialized tasks, including sythesis of membrane lipids and detoxifying drugs, often contain large amounts smooth er2 sets
14the portion of the endoplasmic reticulum that is free of ribosomes2 sets
15have a smooth outer surface. produces steroids as well as playing a role in calcium storage in muscle cells and affects muscle contraction. it also has functions in fat metabolism in liver cells where it detoxifies poisons and drugs.2 sets
16tubular shaped; no ribosomes on membrane; synthesize lipids2 sets
17the portion of the endoplasmic reticulum that lacks attached ribosomes (76)2 sets
18has no ribosomes in its membrane, synthesizes lipids2 sets
19lacks ribosomes2 sets
20connects rough er to the golgi apparats2 sets
21without ribosomes, phsopholipids are made, proteins are packaged into vesicles2 sets
22an organelle; the portion of the e.r. that lacks attached ribosomes2 sets
23er without ribosomes2 sets
24holds quick energy for the cell2 sets
25an extensive system of branching membranes in the cytoplasm that stores calcium ions and synthesises lipids2 sets
26creates lipids or fat2 sets
27produces lipids2 sets
28aids in the production of lipids and carbs2 sets
29smooth membranous network of tubular channels continuous with the rough endoplasmic reticulum where synthesis of lipids and steroids and other processes occur2 sets
30makes or synthesizes lipids, detoxification of drugs/medicines2 sets
31lipid synthesis2 sets
32the major sites of phospholipid synthesis and repairing membranes2 sets
33internal membrane system which contains collections of enzymes that perform specialized tasks, such as synthesis of membrane lipids and detoxification of drugs2 sets
34site of lipid synthesis2 sets
35tubules arranged in looping network play a role in protein synthesis2 sets
36controls reaction rates, produces lipids, drug detoxification2 sets
37in the eukaryotic cell, breaks down lipid soluble toxins in the liver cells and controlls calcuim release in muscle cell contraction.1 set
38::: lipid and steroid hormone synthesis ::: breakdown of lipid-soluble toxins in liver cells ::: control of calcium release in muscle cell concentration1 set
39has no attached ribosomes1 set
40carries proteins from ribosomes and does not have ribosomes attached1 set
