Chapter B9- Respiration Flashcards
What type of reaction is cellular respiration?
What does the energy transferred from respiration supply?
What are the seven life processes?
What does aerobic respiration involve?
What does anaerobic respiration not involve?
What are the three reasons organisms need energy for?
What is the word equation for aerobic respiration?
What is the balanced symbol equation for aerobic respiration?
Exothermic
The seven life processes (MRS GREN)
Movement Respiration Sensitivity Growth Reproduction Excretion Nutrients.
Using oxygen
Without oxygen
Chemical reactions to build larger molecules, movement and keeping warm
Glucose + Oxygen—Carbon dioxide + Water (+energy)
C6H12O6 + 6O2—6CO2 + 6H2O
What is the word equation for anaerobic respiration in muscles?
What is the balanced symbol equation for anaerobic respiration in muscles?
Why is it that in anaerobic respiration much less energy is transferred than in aerobic respiration?
What is the word equation for anaerobic respiration in plant and yeast cells?
What is the balanced symbol equation for anaerobic respiration in plant and yeast cells?
What is anaerobic respiration in yeast cells called?
What three things are produced by the products of anaerobic respiration in yeast cells?
Glucose—Lactic acid (+energy)
C6H12O6—2C3H6O3 (+energy)
Because the oxidation of glucose is incomplete
Glucose—Ethanol + Carbon dioxide (+energy)
C6H12O6—2C2H6O +2CO2
Fermentation
Ethanol- to make alcoholic drinks
Carbon dioxide- to make bread rise.
What is metabolism?
What is the energy transferred by respiration in cells used for by the organism?
What is converted from glucose in metabolism?
What is formatted and from what in metabolism?
What are used to form amino acids and what are these used to do in metabolism?
What reaction is included in metabolism?
What excess is broken down in metabolism and what does it form?
What is oxygen debt (in specific detail)?
The sum of all the reactions in a cell or in the body
Used for the continual enzyme processes of metabolism that synthesise new molecules.
Starch, glycogen and cellulose
Lipid molecules from a molecule of glycerol and three molecules of fatty acids
Use of glucose and nitrate ions to form amino acids which in turn are used to synthesis proteins
Respiration
Excess proteins to form urea for excretion
The amount of extra oxygen the body needs after exercise to react with the accumulated lactic acid and remove it from cells.
What three things increase during exercise?
Why does this occur?
What happens if insufficient oxygen is supplied?
What does the incomplete oxidation of glucose cause and create?
What happens to muscles during long periods of vigorous activity?
Why, how and where is lactic transported to?
What (concerning energy) is the different between aerobic and anaerobic respiration in muscles?
The heart rate, breathing rate and breath volume
To supply the muscles with more oxygenated blood]
Anaerobic respiration takes place in muscles
Causes a build up of lactic acid and creates and oxygen debt
They become fatigued and stop contracting efficiently
Blood flowing through the muscles transports lactic acid to the liver where it is converted back into glucose
Aerobic respiration in muscle cells transfers a lot of energy, whereas anaerobic respiration in muscle cells transfers a small amount of energy.
