Respiration B1 Flashcards
What is cellular respiration?
Respiration is when energy transferred from the breakdown of glucose and is released in the form of ATP. It is an exothermic reaction which is controlled by enzymes.
What is the equation for aerobic respiration?
Glucose + oxygen —> carbon dioxide + water
What is aerobic respiration?
Aerobic respiration is what happens when there is plenty of oxygen available and it is the most efficient way to transfer energy as it produces 32 ATP molecules.
What is anaerobic respiration?
Anaerobic happens without oxygen and it is less efficient as it only produces 2 ATP molecules.
What are all the base pairs and what do they bond to?
Adenine, Thymine, Cytosine and Guanine
A-T ////// C-G
Why is ATP produced?
ATP is produced because energy transferred by respiration cannot be used directly so it’s used to make ATP.
State the function of ATP.
ATP stores the energy needed for many cell processes.
What is the equation for anaerobic respiration in plants and fungi?
Glucose ——> Ethanol + Carbon Dioxide
When would plants have to respire anaerobically?
Plants would have to respire anaerobically when there is little to no oxygen going to them (e.g. waterlogged soil)
Explain how anaerobic respiration takes place in animals.
After vigorous activity, muscles respire anaerobically. During exercise, lactic acid builds up in muscles which makes them fatigued. After stopping exercise, you’ll have an oxygen-debt. You will start breathing heavily to get oxygen back in your body to repay your oxygen debt and break down the lactic acid build-up in your body.
What is the equation for anaerobic respiration in animals?
Glucose ——> Lactic acid
