B9 - Aerobic Respiration and Anaerobic Respiration Flashcards
What is the purpouse of Aerobic respiration ?
The purpouse is to relase energy (oxygen)
Out of gas exchange and respiration , which one is a chemical process and which ones is a pjhsical prcoess ?
Respiration is a chemical process that happens inside cells whereas gas exchange is a physical process .
Where does respiration take place in animals ?
Respiration occurs in all living cells .
When does photosynthesis occur in plants and when do plants respire ?
Plants repsire all the time , photosynthesis occurs during the day where sunlight is present .
Where does respiration take place in plants ?
Respiration occurs in all the cells of plants .
Photosynthesis is the process that provides plants with the enegry they need for life processes , true or false .
False it is respiration that does that .
Digestion is the process that provides animals with energy for growth and movement . True of false
FALSE digestion breaks down food , it is respiration .
Oxyegn is essential for the life process all living organisms , T OR F
False , only for some organisms , some can respire anerobically (which dosen’t require oxygen )
Word equation for Aerobic Respiration ?
Glucose + Oxygen arrow Carbondioxide +water+energy
Symbol equation for Aerobic Respiration ?
C6 H12 04 + 602+ 6C02 +6H20 +energy
What kind of reaction is Aerobic Respiration ?
It is an exothermic reaction .
Meaning of exothermic reaction
Transfers energy to the environment
Meaning of endothermic reaction
Takes in energy from the surroundings .
What is ATP
It is how energy is stored for later use in the body .
How are photosynthesis and aerobic respiration linked ?
Aerboic respiration works in the opposite way of photosynthesis
Link photosynthess and respiration in pllants
PLants produce food byphotosynthesis anf through respiration release energy through it .
What is Anaerobic Respiration
Anaerobic respiration is the process of creting energy without the presence of oxygen .
What are two problems iwth anaerobic respiration ?
- Transfers less energy due to incomplete breakdown of glucose .
- Lactic acid is a mild poison and a build up of it in the bo yd cuases the muscles to stop working and causes msucle craps .
What is anaerobic word equation ?
Glucose arrow lactic acid +energy
Anaerobic symbol equation ?
C6 H12 06 arrow 2C3 H6 03 +energy
What breaks down lactic acid , and what does it break it into ?
Oxygen breaks down lactic acid into carbon dioxide and water .
Where does anaerobic respiration occur ?
It occurs in the cytoplasm .
What is oxygen debt ?
The amount of oxygen required to breakdown lactic acid into cabron dioxide and water .
What is the word equationf or anaerbouc respiration in plants and some microorganisms?
Glucose arrow carbondioxide +Ethanol +Energy transferred to the environment .
What is it called when it happens in yeast
Fermentation
What is oxygen debt ?
The amount of extra oxygen the body needs after exercise to deal with the accumulated Lactic acid .
