smooth endoplasmic reticulum definitions
# Definition Sets
1an endomembrane system where lipids are synthesized, calcium levels are regulated, and toxic substances are broken down.37 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).11 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 er11 sets
4makes molecules such as lipids10 sets
5no ribosomes, makes lipids6 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)5 sets
7the portion of the endoplasmic reticulum that lacks attached ribosomes4 sets
8fatty acid and steroid synthesis; detoxifies toxic substances3 sets
9makes lipids3 sets
10called 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
11lacks ribosomes that populate the surface of the rough endoplasmic reticulum, diversity allows the performance of many functions3 sets
12the portion of the endoplasmic reticulum that lacks attached ribosomes (76)2 sets
13has no ribosomes in its membrane, synthesizes lipids2 sets
14organelle involved with lipid synthesis and drug detoxification2 sets
15creates lipids or fat2 sets
16ribosomes 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
17produces lipids2 sets
18tubular shaped; no ribosomes on membrane; synthesize lipids2 sets
19without ribosomes, phsopholipids are made, proteins are packaged into vesicles2 sets
20er without ribosomes2 sets
21an organelle; the portion of the e.r. that lacks attached ribosomes2 sets
22lacks ribosomes2 sets
23controls reaction rates, produces lipids, drug detoxification2 sets
24aids in the production of lipids and carbs2 sets
25have 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
26the portion of the endoplasmic reticulum that is free of ribosomes2 sets
27makes or synthesizes lipids, detoxification of drugs/medicines2 sets
28smooth membranous network of tubular channels continuous with the rough endoplasmic reticulum where synthesis of lipids and steroids and other processes occur2 sets
29the major sites of phospholipid synthesis and repairing membranes2 sets
30an extensive system of branching membranes in the cytoplasm that stores calcium ions and synthesises lipids2 sets
31tubules arranged in looping network play a role in protein synthesis2 sets
32connects rough er to the golgi apparats2 sets
33site of lipid synthesis2 sets
34part of er that lacks ribsomes1 set
35site of lipid components of the cell membrane1 set
36a network of membranes inside eukarytoic cells inovled in lipid synthesis (steroid in gonads), detoxification (in liver cells), and/or ca2+ storage (muscle cells).1 set
37interconnected passages and sacs without ribosomes synthesizes lipids1 set
38structure: membranous system of sacs and tubules; free of ribosomes; function: site of lipid and steroid (cholesterol) synthesis, lipid metabolism, and drug detoxification1 set
39detoxifies lipid steroid and fatty acid synthesis1 set
40membraneous system of tubules that extend throughout the cytoplasm; not attached to nucleus; sythesizes carbs(sugars) and lipids(fats)1 set
