Science finale 2010

ATP adenosine triphosphate, a molecule that acts as the main energy source for cell processes
Carbohydrate a class of energy-giving nutrients that includes sugars,starches,and fiber; contains carbon, hydrogen,and oxygen
Lipid a type of biochemical that does not dissolve in water; fats and steroids are lipids
protein a molecule that is made up of amino acids and that is needed to build and repair body structures and to regulate processes in the body.
Phospholipid a lipid that contains phosphorus and that is a structural component in cell membranes
Consumer an organism that eats other organisms or organic matter
producer an organism that can make its own food by using energy from its surroundings
Nucleic acid a molecule made up of subunits called nucleotides
Decomposer an organism that gets energy by breaking down the remains of dead organisms or animal wastes and consuming or absorbing the nutrients
Archaebacteria a kingdom made up of bacteria that live in extreme environments
Cell membrane a phospholipid layer that covers a cell's surface and acts as a barrier between the inside of a cell and the cell's environment
Eubacteria a kingdom that contains all prokaryotes except archaebacteria
Eukaryote an organism made up of cells that have a nucleus enclosed by a membrane; eukaryotes include animals,plants, and fungi but not archaebacteria or eubacteria
Nucleus in a eukaryotic cell,a membrane-bound organelle that contains the cell's DNA and that has a role in processes such as growth,metabolism,and reproduction
Organelle one of the small bodies in a cell's cytoplasm that are specialized to preform a specific function
prokaryote an organism that consists of a single cell that does not have a nucleus
Ribosome a cell organelle composed of RNA and protein ;the site of protein synthesis
cell wall a rigid structure that surrounds the cell membrane and provides support to the cell
chloroplasts the organelle that uses the energy of sunlight to make food
cytoskeleton a web of proteins in the cytoplasm. It keeps the cell's membranes from collapsing.
Endoplasmic Reticulum a system of membranes that is found in a cell's cytoplasm and that assists in the production, processing, and transport of proteins and in the production of lipids
Golgi complex cell organelle that helps make and package materials to be transported out of the cell
Lysosomes a cell organelle that contains digestive enzymes
Mitochondrion in eukaryotic cells, the cell organelle that is surrounded by two membranes and that is the site of cellular respiration
Multicellular made of many cells- benefits-larger size, longer life, specialization
Gene one set of instructions for an inherited trait
RNA ribonucleic acid a molecule that is present in all living cells and that plays a role in protein production
Nucleotide in a nucleic-acid chain, a subunit that consists of a sugar, a phosphate, and a nitrogenous base
DNA deoxyribonucleic acid,a molecule that is present in all living cells and that contains the info. that determines the traits that a living thing inherits and needs to live
Mutation a change in the nucleotide-base sequence of a gene or DNA molecule
Substitution when the wrong base is used
Insertion Extra base is added
deletion a base is left out
At what stage are the chromosomes copied stage 1
Are lipids hydrophobic or hydrophilic hydrophobic
lipids are compounds that can not_______ mix with water
like carbohydrates,some lipids ____ store energy
Other lipids form the_____ membranes of cells
Phosolipids are... the molecules that form much of the cell membrane
T or F The head of the phosolipids molecule is attracted to water. T
T or F When phospholipids are in water the tails separate F When phospholipids are in water the tails come together
Fats and oils are... lipids that store energy
ATP is the ... major energy-carrying molecule in the cell
The energy in carbohydrates and lipids must be transfered to ATP,which then provides fuel for cellular activities
Nucleic acids are large molecules made up of molecules called nucleotides
There was to much info to post up on all of those pages so i just put the vocab and some questions up here are all the page numbers she told us to study hope this helps a little
