The Amazing Cell Flashcards
Actin
Contractile muscle (in your heart and lungs) develop more when a sprinter, twitcher, ect.
Works with myosin
Used for cell division
Cytoskeleton
Made of microtubulars
Multi nucleated
Muscle cells, mitochondria
Purpose of a cell?
Produce protein
Mitochondria
Produces 95% of energy comes from here
Power house
Where ATP is produced
Where does the Kreb Cycle take place?
Mitochondria
What happens when there is a high demand of mitochondria?
Mitochondria will reproduce itself through pinching off from itself
Are ribosomes located in prokaryotic or eukaryotic cells?
Both
Where is the endoplasmic riticulum located?
Connected to nucleus
Characteristics of endoplasmic riticulum…
Continuous channel Provides more surface area 30 times larger than plasma membrane Eliminate drugs Home of ribosomes
What does smooth ER aid in?
Making of lipids
What is the Golgi apparatus involved with?
Getting protein where it needs to go
What are vesicles?
Little containers
Lysosomes..
Engulf bad materials and break it down
Packing receiving
Peroxisomes…
Detoxer!
Have materials to take toxins and bring it down to water
What do peroxidases do?
Take free radical and changes to hydrogen peroxide
What do catalases do?
Take hydrogen peroxide and change to water so our body can use it
What influences a reaction?
Temperature and environment
How does temperature effect velocity?
When temp increased, velocity is increased. Velocity provides the energy for reaction
What happens when you increase concentration?
Increases availability
What is activation energy?
Energy requires for reaction to happen
Ex. Kitchen match (just to get it going)
What is an exothermic reaction?
Give off energy (phosphate breaks off ATP to become ADP to become energy)
What is an endothermic reaction?
Ending product has more energy than original reaction
Ex. Seed turning to apple/tree
Characteristics of enzymes:
Lower activation energy and speed up rate of reaction
Catalyst
Helps chemically speed up rate of reaction
Properties of water:
- Very polar (pulls on positive and negative)
- Universal solvent- Breaks down most things that are hydrophilic
- Ionic bonding substance loves water
- Solute- One that it dissolves (salt)
- Blanketing- Negative side of water surrounds pos. solute
- Hydrophobic- Usually electrically neutral, usually very non polar
- High heat adversion
- Adhesive- Sticky to itself
- Solinity will lower heat of vaporization
- Water gets bigger when frozen
- Lubricant- lines everything in body
Salt…
Ironically bonded substance
Inorganic
Conducts electricity
Osmotic fluid
Blood and water will mix
Characteristics of Acids
Ironically bonded When added to water, freely release hydrogen ion Proton donor Ionize in water H+
Characteristics of bases
Receive proton Proton receptor OH- High concentration Alkaline compounds ironically bonded, ionize in water
