Exit Ticket: Review of Macromolecules and Water

Review of Macromolecules Mini match: connect with a line A macromolecule made of CHO in a 1:2:1 ratio Carbohydrates A macromolecule made of CHO shaped like an "E" lipid A macromolecule made of CHON protein A macromolecule made of CHONP nucleic acid Review of pH Mini Match: connect with a line Has a pH above 7 Base Has a pH below 7 Acid Has a pH of 7 Neutral A pH of 6 is a Weak acid A pH of 1 is a Strong acid A pH of 8 is a Weak base A pH of 13 is a Strong base Click on the blanks for a word bank to complete each sentence. OH- is the symbol for a hydroxide ion and H+ is the symbol for a hydrogen ion. If a solution has a lot of hydroxide ions then it is an acid and if it has a lot of hydrogen ions then it is a base. If a solution has a pH of 6.9 then it will still be a weak acid and if it has a pH of 7.1 then it will be a base, just a weak one. Life typically operates in a very narrow range of pH, a slightly alkaline range of 7.35 to 7.45. Water review Mini Match: connect with a line How many hydrogens are in a water molecule 2 How many oxygen are in a water molecule? 1 Sugar dissolved in water is called a solution Sugar is an example of a solute Water is a really good solvent Click on the blanks for a word bank to complete the sentences. Sugars tend to end in the letters "ose," for example glucose and sucrose. Enzymes usually end in the letters "ase," for example lactase and sucrase. Enzymes are often named for the reaction they catalyze, such as lactase breaks down lactose. Enzymes cause chemical reactions to speed up. Enzymes have a specific shape and can be destroyed by temperature or pH.
