B9 - Respiration Flashcards
what is the word equation for aerobic respiration?
glucose + oxygen —> carbon dioxide + water + energy
What is the symbol equation for aerobic respiration?
C6H12O6 + 6O2 —> 6CO2 + 6H2O + energy (ATP)
Where does aerobic respiration take place?
mitochondria
Where does anaerobic respiration take place?
cytoplasm
Endothermic reactions ___ __ heat/ energy.
takes in
Exothermic reactions ____ __ heat/energy.
gives out
What type of reaction is photosynthesis?
endothermic
When you complete exercise your ____ increases.
temperature
What type of reaction is respiration?
exothermic
What are the responses to exercise?
increased heart rate
increased breathing rate
increased temperature
glycogen is broken down
increased depth of breathing
Why does your heart rate increase when exercising?
blood pumping faster meaning more oxygen getting to blood and an increase in glucose meaning increase in energy released and more respiration.
Why does your breathing rate increase when exercising?
increase gas exchange
increase in oxygen
removes carbon dioxide faster
Why does your breathing depth increase when exercising?
removes co2 faster
increase in oxygen
increase gas exchange
Why is glycogen broken down when exercising?
more glucose moves into cells
more glucose in the blood
Over using a muscle or short rapid requirements lead to _____ respiration.
anaaerobic
Anaerobic respiration is when there is not enough ____ present.
oxygen
When overusing a muscle there is not enough oxygen present this leads to the production of….
lactic acid
What is the word equation for anaerobic respiration in animals?
Glucose —-> lactic acid + energy
What is the symbol equation for anaerobic respiration in animals?
C6H12O6 —-> 2C3H16O3 + 2ATP
What is a cramp?
build up of lactic acid
How is a cramp caused?
lack of oxygen to muscles
How do you get rid of cramps?
by restoring the blood supply to the muscles
Why does restoring blood flow relieve cramps?
more oxygen and glucose flowing to muscles.
able to switch back to aerobic respiration instead of anaerobic.
able to move lactic acid out of muscle cells.
What does anaerobic respiration result in?
oxygen debt
What does oxygen debt do?
the extra oxygen oxidises lactic acid to carbon dioxide and water.
What is the word equation for oxygen debt or lactic acid whatever?
lactic acid + oxygen —-> carbon dioxide + water
What is the word equation for anaerobic respiration in non-animals?
glucose —-> ethanol + carbon dioxide
What is the symbol equation for anaerobic respiration in non-animals?
C6H12O6 —-> 2C2H5OH + 2CO2
Lactic acid causes muscles to…
contract less
What does EPOC stand for?
excess
post-exercise
oxygen
consumption
What is the word equation for anaerobic respiration in plants and yeast?
glucose —> Ethanol + Carbon dioxide
Why is anaerobic respiration useful in every day life?
it is used in yeast in the brewing industry. Ethanol is used for alcoholic drinks.
It is using in yeast in bread making.
What is metabolism?
the sum of all the reactions in a cell or body.
What are the 7 types of metabolism reactions?
Respiration.
Glucose —-> starch (in plants).
Glucose —-> cellulose (in plants).
Glucose —-> glycogen (in animals).
Formation of lipids from glycerol and fatty acids.
Use of glucose and nitrate ions to form amino acids for proteins.
Breakdown of excess protein into urea which is excreted.
