Protein Synthesis
Involves mRNA and ribosomes and takes place inside the cytoplasm
Nuclear Pore Complex
Sits in the middle of the nuclear pore and controls movement of substance through the pore
The sight for RNA synthesis and the sight for the assembly of ribosomes
Found in every eucaryotic cell. The powerhouse and is the sight of ATP production
Finger like projections in the inner membrane of the mitochondria
Empty fluid filled space inbetween the inner membrane of the mitochondria
found in certain parts of plant cells. This is where photsynthesis takes place. Has an inner and outer membrane
stacks of disk shaped membranes where cholrophyl is found
Fluid material inside individual thylakoids
Rougn Endoplasmic Reticulum
consists of a series of membranes stacked on top of each other. Flattened membrane sacks in which ribosomes are scattered on top
Smooth Endoplasmic Reticulum
Tubular in shape and connected to the Rough ER. Has three functions
Golgi Complex
Cup shaped in appearance. it packages proteins destined for export from the cell, adds carbohydrates to proteins, and produces lysosomes
Vesicle with 40 different digestive enzymes inside
Used to support the rest of the cell and consists of long fibers called microtubules and microfilaments
Provides and maintains cell shape, track along which various organelles and vesicles move, make up centrioles and cilia/flagella
Dynein Arms
help doublets move past one another so the cilia can move
straight, long filament, composed of the protein actin. Maintains cell shape, and can perform in some contractile events like cell division.
Kinetic energy
the energy of motion
Potential Energy
Stored energy
Laws of Thermodynamics
1. Energy can be converted from one form to another but it cannot be created or destroyed
2. Every energy conversion results in an increase in the amount of non usable or wasted enrgy in the universe
non usable or wasted energy. Constantly increasing
Free Energy
the energy available to do work
a substance that speeds up the rate of a reaction but is not consumed by the reaction
Biological catalysts that are unchanged by the reaction and lower the amount of activation energy required
Active Site
the site on the enzyme to which the substrate attaches
Induced Fit Model
Active site is not complementary to the substrate. As the substrate approached, the active site will induce a precise fit
pH optimum
the pH at which the enzyme is maximally active
Metabolic Pathways
series of enzyme catalized reactions in which the product of one reaction becomes the substrate for the next
small inorganic ions and some organic molecules
refers to small organic molecules required for enzyme catalized reactions
removal of electrons from a compound
Biological Oxidation
occurs inside a cell without heat
Two ways cells capture energy from glucose breakdown
ATP and Reduced Coenzymes (NADH)
addition of a phosphate group to an organic molecule
the addition of electrons to a molecule
