| Question | Answer |
|---|---|
| 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 |
