Bellwork Quiz 10/1
| Question | Answer |
|---|---|
| Which of the following statements are true? | 2, 3, and 4 |
| Most biological macromolecules contain carbon, hydrogen, and oxygen atoms. Which of these has them in a 1:2:1 ratio? | Carbohydrates |
| Which of the following is not a function of polysaccharides? | Storage of genetic information |
| The overall equation for cellular respiration is... | oxygen + glucose --> water + carbon dioxide + ATP |
| If used for cellular respiration, this mass will eventually be converted into carbon dioxide, ____ , and ____. | Water, energy (ATP) |
| Based on the illustration, what happens to most of the mass gained by the plant cell through photosynthesis? | The mass produced by the photosynthesis reaction is used by the plant to fuel respiration and is turned into carbon dioxide, water, and energy. |
| Which of the following is not part of cellular respiration? | the Calvin cycle |
| C6H12O6 (glucose) + 6O2 (oxygen) + ADP + P --> 6CO2 (carbon dioxide) + 6 H2O (water) + molecule A The molecule referred to as "molecule a" in the equation above is... | ATP |
| Aerobic cellular respiration takes place in four stages: | glycolysis, linking step, Krebs cycle, ETC |
| The process of photosynthesis can be represented by the chemical formula... | 6CO2 + 6H2O --> C6H12O6 + 6O2 |
| Light energy is transformed into chemical energy during... | Photosynthesis |
| What reactant was the biggest contributor to making the glucose? | CO2 |
| Photosynthesis is the conversion of light energy into the chemical bonds of the glucose. The molecule that absorbs the light is the ____ and the occurs in the ____. | Chlorophyll, thylakoid |
| A cell with 1% solute concentration is placed in a beaker with 5% solute concentration. What will happen to this cell over time? | The cell will lose water and shrink |
| In light reactions, ATP is synthesized when hydrogen ions move down the concentration gradient through the enzyme ATP synthase. What type of transport is this? | Facilitated diffusion |
| According to the model of photosynthesis below, which situations(s) will likely lead to larger production of oxygen from plants? | 1. sunny days |
| How will the summer drought affect photosynthesis? | Water will be a limiting reactant. As a result, less glucose will be produced. There will be less CO2 taken in and less O2 out. |
| During photosynthesis, sugar glucose is produced from carbon dioxide, water, and sunlight. What statement BEST explains what happens during photosynthesis? | Atoms of compounds are rearranged to form new compounds. |
| What best describes what happens when a cell is placed into a hypertonic environment? | The excess solute in the environment causes water to move out of the cell |
| Which of the following accurate describes diffusion? | the passive movement of molecules from a high to low concentration |
| If stranded on a deserted island with no freshwater, it is not advisable to drink sea water. Why not? | The salt in the body creates a hypertonic solution around cells, which causes water to diffuse out of the cells and make them shrink. |
