Flashcards do conjunto (29)
- 1What is a cellSmallest unit of life.
Contain organelles
Each cell maintains its own & body homeostasis. - 2Cell Structure3 Major parts:
Nucleus
Cytoplasm- h20,Organelles= little organs
Plasma (cell) membrane- outer coat. - 3How many nucleus does cells haveAll cells have normally 1 nucleus except erythocytes (Red Blood cells) dont have nucleus
Skeletal cells have many nucleus (S/M) - 4NucleusControls cell division
Controls protein synthesis
Contains DNA - 5OrganellesPerforms tasks associated with cell function.
Cytoskeleton
Mitrochondria
ribosomes
Endoplasmic
reticulum
Golgi Apparatus
Lyosomes - 6CytoskeletonGives the cell its shape and movement e.g in muscles.
Is made of protein strands called atkin and myosin - 7MitochondriaMakes ATP- (Adenosine triphosphate- cell energy)
Turns Glucose into energy - 8RibosomesMakes proteins by joining amino acids together
- 9Endoplasmic ReticulumRough- Studded with ribosomes fods and modifies proteins
Smooth- Detoxifies and stores CA++ transport store lipids - 10Golgi ComplexModifies and packages proteins end result either becomes part of the cell or secreted by the cell or remains inside the cell
- 11LysosomesOrganelle that remains inside the cell
Contains enzymes that destroy harmful substances that might enter the cell. E,g bacteria viruses and toxins - 12The cell (Plasma) membraneIs made up of
lipids
Cholestrol
Proteins
Carbohydrates - 13Membrane LipidsPhospholipid bilayer hydrophilic (heads) freely react to water
Hydrophobic- lipid tails that repel water - 14How are molecules formedThey are formed when 2 or more atoms are joined together.
- 15CholesterolWedged between some tails gives support
Carbon fat and protein. - 16Membrane proteinsUse for transport things in or out of the cell.Receptors for chemical binding.
- 17Passive TransportNO ATP used e.g
diffusion
facilitated diffusion
filtration
osmosis - 18DiffusionRandom movement down a concentration gradient. Spreads evenly over the cell can either go in or out.
- 19Faciliated diffusionProteins assist to move it through the cell by changing shape.
- 20OsmosisWater moves through the protein if there is a concentration difference.
- 21ATPRequires energy going against the concentration gradulant
Salt Na+ = sodium
CI+ = Cloride - 22Vesicular transportis a bubble inside a cell
Exocytosis- bubble for export
Endocytosis- bubble for import. - 23BiochemistryIs structures/ properties of living things
- 24MatterEverything is made of matter.
Solid= holds together
Liquid= Move around
Gas= moving not touching - 25ElementCompound of the same atom.
4 make up your body Carbon, hydrogen,oxygen and nitrogen. - 26Mixtures2 or more elements mixed together but retaining their individual properties
- 27Compund2 or more elements bounded together individual properties lost cant go back
- 28Neutronsno charge
- 29ElectronsCan be added or removed to make ions some give away electrocytes or take extra electro these make ions ions in solution are electrocytes
