Cells Flashcards
Hydrogen bond
Forms in water molecules between oxygen and hydrogen
Protein
Made up of amino acids and produced in the rough ER
Polymer
Is a large molecule formed from repeating subunits of smaller molecules (ex, Proteins - Amino Acids)
Dehydration synthesis
Forms polymers from monomers by removing water
Hydrolysis
Produces monomers from polymers by adding water
Short term energy Carbohydrates
Glucose
Long term energy carbohydrate
Glycogen
Monosaccharides
Single unit sugars (carbohydrate)
Polysaccharides
A carb with large amounts of monosaccharide molecules
DNA
Controls all cell activities stored inside the nucleus
RNA
Directs protein synthesis
ATP
Produced inside the mitochondria during the process of cellular respiration
Lipid
Hydrophobic used as insulation
Saturated fat
No double bonds between carbon
Unsaturated fat
Have one or more double bonds between carbons
Cell theory
All living organisms are made up of one or more cells
The cell is the basic unit of life
All cells come from pre-existing cells
Prokaryotes
No nucleus or membrane bound organelles
Eukaryotes
Has a nucleus and membrane bound organelles
Fluid mosaic pattern
Diagram of the cell membrane
Shows the protein and lipid particles
Diffusion
Molecules move high to concentration to low concentration until equally distributed
Osmosis
The movement of water through a selectively permeable membrane is osmosis. Requires no energy
Active transport
Moving from low to high concentration gradient
Endocytosis
Molecules moving from outside to inside the cell with the cell creating a vacuole
Phagocytosis
When molecules that are taken are huge
Exocytosis
Vacuole fuse with membrane and contents are deposited outside the cell
Hypertonic Solution
The cell has a lower concentration of a solute therefore water travels from the cell to the solution
Hypotonic
Water enters the cell to balance the levels of solute
Isotonic solution
Equal amount of solute inside and outside the cell
The various enzymes in our body are
Protein
What forms from a long chain of glucose molecules
Startch (carbohydrate)
What are long chains of amino acids
Protein
Glycogen
Polysaccharide of glucose (carbohydrate)
What is a peptide bond
The bond of 2 or more amino acids
Pinocytosis
When the molecules that are taken in are tiny
Nucleus
Controls all functions in the cell
Nuclear envelope
Double membrane that protects the nucleus
Rough Endoplasmic reticulum
Ribosomes attached here. Produces protein
Smooth ER
No ribosomes attached makes fat, detoxifies drugs
Golgi Apparatus
Packages sorts and stores protein
Mitochondria
Performs cellular respiration and produces ATP
Cytoplasm
Holds organelles in their place
Cytoskeleton
The frame that supports the cell
Chloroplasts
Plant organelle that captures light and turns it into ATP energy
Cell Wall
Plants only, located outside the plasma membrane provides support and additional protection
