1785633976 | What is a calorie? How do cells use a high-calorie molecule such as glucose? | - the amount of energy needed to raise the temperature of 1 gram of water 1 degree celsius - cells break down the glucose releasing the stored energy a small amount at a time | 10 | |
1785633977 | How is glucose changed during glycolsis? What products are produced as a result of glycolsis? | - glucose is broken into 2 molecules of pyruvic acid -ATP molecules and high-energy electrons that are picked up by NAD+ | 11 | |
1785633978 | What are the two pathways that might follow glycolysis? What factor can determine which of those pathways a cell might follow? | - After glycolsis, if oxygen is avialable, a cell might carry out the rest of cellular respiration. - If oxygen is not available, some cells carry out the rest of fermentation | 12 | |
1785633979 | Use formulas to write a chemical equation for cellular respiration. Label the formulas with the names of the compounds. | 602 + C6 H12 O6 —> 6CO2 + 6H2) + Energy (Oxygen + Glucose —> Carbon Dioxide + Water + Energy) | 13 | |
1785633987 | Draw and label a mitochondrion surrounded by cytoplasm. Indicate where glycolsis, the Krebs cycle, and the electron transport chain occur. | ![]() | 14 | |
1785633980 | How is NAD+ involved in the products of glycolosis? What happens to a cell's NAD+ when large numbers of high-energy electrons are produced in a short time? | - NAD+ picks up high energy electrons - the high-energy electrons quickly fill all of the cell's available NAD+ | 15 | |
1785633981 | Which two compounds react during fermentation compares with alcoholic fermentation. Which reactant(s) do they have in common? | - pyruvic acid & NADH - NADH passes high-energy electrons to pyruvic acid | 16 | |
1785633982 | Write equations to show how lactic acid fermentation compares with alcoholic fermentation. Which reactant(s) do they have in common? | Lactic Acid fermentation: glucose —> lactic acid Alcoholic Fermentation: glucose —> alcohol + CO2 - both have glucose as the reactant | 17 | |
1785633983 | How are fermentation and cellular respiration similar? What is the main difference between their starting compounds? | - both processes break down glucose and release the energy stored in the molecule & both start with glycolsis - cellular respiration requires oxygen and fermentation occurs WITHOUT oxygen | 18 | |
1785633984 | Summarize what happens during the Krebs cycle. What happens to the high-energy electrons generated during the Krebs cycle? | - Pyruvic acid is broken down into carbon dioxide in a series of reactions that give off energy - they are picked up by a series of electron carriers, and the energy is used to convert ADP into ATP | 19 | |
1785633985 | How is ATP synthase involved in making energy available to the cell? | ATP synthase is a large protein through which hydrogen ions (H+) pass, converting ADP into high-energy ATP. | 20 | |
1785633986 | When runners race for about 20 minutes, how do the bodies obtain energy? | they get energy from ATP in their muscles produced by lactic acid fermentation. In 20 minutes, bodies use cellular respiration to use stored carbs to make ATP | 21 |
