Q

Cells are made up of what 3 parts?

Study These Flashcards
A

Nucleus, cell membrane, cytoplasm

23
Q

What are the functions of the proteins found in cell membranes?

Study These Flashcards
A

Structure, recognition, channel, receptors, transport, adhesion

24
Q

Helps with the stability of the cell membrane, makes less permeable for water soluble things

25
Combination of phospholipid and embedded proteins/cholesterols, not in a stationary position
Fluid mosaic model
26
Two types of transport mechanisms account for movement of various substances across cellular membranes (2)
Passive and active
27
What are the 4 types of passive transport?
Diffusion, carrier proteins, osmosis, ion channels, filtration
28
What are the 5 types of active transport?
Na-K pump, proton pump, phagocytosis, pinocytosis, exocytosis
29
Where are organelles found?
Cytoplasm
30
Clear liquid in cytoplasm
Cytosol
31
Inner membrane of mitochondria; hold enzymes needed in energy transformations to make ATP
Cristae
32
What two things make up ribosomes?
Proteins and RNA
33
Where are ribosomes made?
Nucleolus
34
What organic compounds do ribosomes synthesize or make?
Proteins
35
What does the rough ER make?
Protein
36
What does the smooth ER make?
Lipids
37
How does the Golgi work with the ER of a cell?
Vesicles travel of the Golgi and carries the chemicals throughout the cell
38
What protein makes up microfilaments?
Actin
39
What does the shape of the cell reflect?
Function
40
Performs special functions of the cell
Organelle
41
How many cells make up the human body?
75 trillion
42
Why do liver and muscle cells have more mitochondria than other types of cells?
Need lots of energy for movement and detoxifying materials
43
Why can cells not survive if they are totally isolated from their environment?
Doesn't have the nutrients they need and won't get things from other cells
44
What is the purpose of the carbohydrate tails attached to some integral proteins?
Cellular ID, sees what does and doesn't belong
45
Describe the outer covering of the mitochondria
Double layered, increases surface area
46
What organelles are the most numerous inside cells?
Ribosomes
47
Requires no energy and works with concentration gradient
Passive
48
Requires energy and doesn't work with concentration gradient
Active
49
Consists of inner and outer lipid bilayer membranes
Nuclear envelope
50
Made up of 2 chromatids connected by a centromere
Chromosomes
51
Consists of loosely coiled fibers of DNA and protein
Chromatin
52
House enzymes that catalyze synthesis of bile acid and detoxification of hydrogen peroxide, alcohol, and break down lipids and biochemicals
Peroxisomes
53
Region near nucleus where centrioles are found that helps organize the spindle fibers during cell division
Centrosome
