| Question | Answer |
|---|---|
| Where does glycolysis occur and how many ATP are produced? | In the cell cytosol, 2 ATP are produced |
| Where does the Krebs cycle take place? how many ATP are produced? | In the matrix in the mitocondria, 2 ATP's are produced |
| Where does the Electron transport chain occur and how many ATP are produced? | In The cristae (folded membrane), 34 ATP produced |
| What is an anabolic reaction? | A reaction the requires energy. Makes chemical bonds |
| What is a catabolic reaction? | A reaction that produces energy. It breaks chemicals bonds and make larger molecules into smaller molecules. |
| What is the main purpose of enzymes? | Enzymes are proteins that speed up reactions. They are also called biological catalysts. |
| Starting with A, what do all enzymes have? | An active site |
| What replace T in the base pairings of DNA | U |
| Complete the complementary strand of this DNA: ATTCATCCG | TAAGTAGGC |
| the bases are read in codes | Triplet |
| What are exons? | The instructions required to make a protein |
| What are introns? | They are not part of the code for a protein, but are involved in the functioning of a gene |
