Respiration Flashcards
What cellular activities may energy generated by respiration be used for in the body
Muscle cell contraction
Cell division
Protein synthesis
Transmission of nerve impulses
Which type of respiration is more efficient and why?
Aerobic respiration produces a larger yield (number) of ATP
Explain why cells, such as muscle or sperm cells, contain a large number of mitochondrion
They require a lot of energy to perform their functions
In which cell structure(s) is
A aerobic respiration carried out
B fermentation carried out
A Mitochondria
B Cytoplasm
Draw a simple diagram to show both stages of fermentation in plants and yeast
Glucose-2ATP->Pyruvate->CO2 + ethantol
Write the summary equation for fermentation in plants and yeast
Pyruvate-> CO2->Ethanol+energy
where is the process of aerobic respiration completed
Mitochondria
Where is the process of fermentation completed
Cytoplasm
Where in the cell does respiration begin
Cytoplasm
How many molecules of ATP are produced via the fermentation pathway
2
What is pyruvate broken down into during the second stage of fermentation in plant and yeast cells
CO2 and ethanol
What is pyruvate broken down into during the second stage of fermentation in humans
Lactate
What is the overall word equation for fermentation in humans
Pyruvate-> lactate + energy
Draw a simple diagram to show both stages of aerobic respiration
Glucose->pyruvate->CO2+Water+ATP

Many
Name the products of the second stage of aerobic respiration
Co2
water
lots of ATP
Name the raw materials of the second stage of aerobic respiration
pyruvate + oxygen
How many molecules of ATP are produced in the first stage of respiration
2
Name the products of the 1st stage of both types of respiration
pyruvate and 2ATP
Name the raw material of the first stage of both types of respiration
Glucose
Name the products of aerobic respiration
CO2 + water
Name the raw materials of aerobic respiration
glucose and O
what is the overall equation for aerobic respiration
Glucose + oxygen -> CO2+ water+ energy
What is it meant by the term fermentation
respiration that occurs in the absence of oxygen
What is it meant by the term aerobic respiration
respiration that occurs when oxygen is present
Name the high energy molecule which stores the energy produced during respiration
ATP
what substance controls the reactions in respiration
enzymes
What is respiration
the chemical energy stored in glucose is released by all cells
