Biology 111 part 2
| Term | Definition |
|---|---|
| Similarities between DNA and RNA | DNA and RNA are both made of monomers and they both have 3 nitrogenous bases. |
| Differences between DNA and RNA | RNA is a single-stranded molecule while DNA is a double-stranded RNA contains ribose while DNA contain deoxyribose RNA contains uracil while DNA contain thymine |
| Base | Is anything that releases hydroxide ions when placed in water _pH grater than 7 |
| Acidic | Is anything the releases hydrogen ions one place it in water _pH less than 7 |
| Nucleotides | Are the building blocks of nucleic acids |
| Subunits of macromolecules | Sugars (carbohydrates) Fats (lipids) Animo acid (protein) DNA and RNA (nucleic acids) |
| Four main types of macromolecules | :Proteins :carbohydrates :lipids :Nucleic Acids |
| ATP | Is the Energy currency of cells |
| Polymers | Is a large molecule made of smaller molecules called monomers |
| Five nitrogenous Bases that make up DNA and RNA | >Adenine >Guanine >Cytosine >Thymine >Uracil |
| Steroid | Is a type of lipid made up of four Carborings attached to molecules that vary from one steroid to the next |
| The pH scale is used to measure | How acidic or basic a substance is |
| Matter | Is anything that takes up space and has mass |
| Buffer | Prevent dramatic changes in pH |
| A pH of 7 is | Considered neutral |
| The PH scale-ranges | From 0 (most acidic) to 14 (most basic) |
| DNA is | Deoxyribonucleic acid |
| RNA is | Ribonucleic acid |
| Cofactors that are composed of organic molecules are called | Coenzymes |
| Chemical Bound types from strongest to weakest | Covalent Bonds- strongest Ionic Bond- Strong Hydrogen- Weak |
| Isotopes | Are atoms that have the same number of protons but different in the number of neutrons |
| Atomic number | Is the number of protons in the Atom nucleus |
| Compound | Two or more elements that combine together |
| Radioisotopes | Are Radioactive isotopes |
| Level of organization of a protein | -Primary Structure -Secondary Structure -Tertiary Structure -Quaternary Structure |
| ATP is required | To keep organs alive, cells are also required of energy When phosphate bond is broken energy is released |
| Element | A pure form of matter containing only one kind of atom |
| Covalent bond | Form between atoms that can share electrons rather than donating or reviving them |
