Unit Two: Continued Overall Cell Knowledge Flashcards
1
Q
What are features of the endoplasmic reticulum
A
- network within the plasma
- flattened sacs (cisterna)
- tubular membranes
- continuous with the outer nuclear membrane
2
Q
What are features of the Golgi Apparatus
A
- stack of flattened vesicles (cisternae)
- no ribosomes
- process and package of protein
- found in cells with rough ER
3
Q
What are features lysosomes and secratory vesicles
A
- particle digestion hydrolases
- rough ER –> Golgi –> lysosme
- sequestration
- high degree of glycoslyation
4
Q
What is the Rough Endoplasmic Reticulum
A
- dots: ribosomes
- polypeptide synthesis
- quality control
5
Q
What is the Smooth Endoplasmic Reticulum
A
- no dots = no ribosomes
- produces lipids and steroids
- detoxification (asborbs toxins)
- storage for skeletal muscle
6
Q
What are Lysosomes
A
- membrane bound vesicles
- less than 30 enzymes
- found in animal cells
- formed by **budding from Golgi Appartatus **
- operate a lower pH level
7
Q
What is Autophagy
A
refers to the digestion of cells organelles
8
Q
What is Phagocytosis
A
cellular ingestion of extracellular particles
9
Q
What is the Mitochondria
A
- powerhouse of the cell
- makes energy through ATP
- has its own ribosomes (protein synthesis)
10
Q
Facts about the Mitochondria
A
1. Aerobic Respiration
- consumes oxygen to make ATP
- produces carbon dioxide and water
2. Mitochondrial Number
- more mitochondria
- more oxygen utilization to make ATP
3. Contains Proteins
- 2 sources of mitochondrial protein: nuclear protein import AND protein manufactoring
