level questions: Level 1 of Respiration
| Question | Answer |
|---|---|
| What type of cells does respiration take place in? | all living cells |
| What is respiration? | the process by which living cells release energy from food |
| Why do cells need energy? | cell growth and division, cell movement, active transport across the membrane, release of heat to keep warm |
| What happens if an organism ceases to respire? | it dies |
| What are the raw materials of aerobic respiration? | glucose and oxygen |
| What is the useful product of aerobic respiration? | energy |
| What are the waste products of aerobic respiration? | water and carbon dioxide |
| How do glucose and oxygen get into the cell? | they diffuse into cells through the cell membrane (diffusion) |
| Where is the energy in the glucose molecule? | in the chemical bonds |
| What is the purpose of aerobic respiration? | to move the chemical energy held in glucose molecules into molecules of adenosine triphosphate (ATP) |
| Where does the energy from a glucose molecule end up? | In the ATP |
| What type of foods tend to have more energy? | fatty foods |
| What is the equation for anaerobic respiration in animals? | glucose -> energy+lactic acid |
| What is the equation for anaerobic respiration in yeast? | glucose -> energy + alcohol + carbon dioxide |
| What is anaerobic respiration? | During vigorous exercise the supply of oxygen to the muscles does not keep up with the demand and fermentation is used. The muscles become less efficient and ache due to the build up of lactate. |
