Cellular Respiration Flashcards
The plant takes the raw
materials (______), puts
them together using energy
(_____), & synthesize the
cake.
(CO2 & H2O), heat
Nutrient =
Chemical Energy =
Nutrient = Glucose
Chemical Energy = ATP
Is the process by which organisms
obtain the energy they need by
releasing the chemical energy
stored in nutrients and transferring
that energy into ATP
Cellular Respiration
Cellular Respiration occurs in the
Mitochondria of Eukaryotic organisms
Respiration occurs on the
cristae
Two Types of Respiration
Aerobic Respiration
Anaerobic Respiration
– needs oxygen to release the energy in food
C6H12O6 + 6O2 6CO2 + 6 H2O + 36 ATP
Aerobic Respiration
can release the energy from food without the
need of oxygen. (Some bacteria & yeast)
Anaerobic Respiration
C6H12O—2 CO2 + 2 Ethanol + 2 ATP = alcoholic fermentation
C6H12O6—2 Lactic Acid + 2 ATP = lactic acid fermentation
C6H12O—2 CO2 + 2 Ethanol + 2 ATP = alcoholic fermentation
C6H12O6—2 Lactic Acid + 2 ATP = lactic acid fermentation
Also known as fermentation
Anaerobic Respiration
Occurs in the cytoplasm of yeast, some bacterial
cells
Anaerobic Respiration
Since the organisms are very small and their
needs are simple, they do not need much ATP
Anaerobic Respiration
Anaerobic Respiration occurs in two steps :
Glycolysis and Fermentation
The 2 Pyruvic Acids will break down into:
- Alcohol + CO2(yeast and some bacteria)
- Lactic Acid (bacteria, us – more later)
Occurs in the mitochondria
Aerobic Respiration
Yields more ATP per molecule of
glucose (36 – 38 molecules) of
ATP/Glucose
Aerobic Respiration
Occurs in 3 basic steps
Aerobic Respiration
3 basic steps in Aerobic Respiration
- Glycolysis
- Krebs Cycle
- Electron Transport Chain
in the Mitochondria, the 2 Pyruvic acids
are broken down, releasing CO2 & producing 2 ATP
Krebs Cycle
Using 2 ATP as activation energy, a glucose molecule is broken down into 2 Pyruvic Acid molecules. 4 ATP are
produced, leaving 2 ATP netted.
Glycolysis
Oxygen combines with
hydrogen 32 ATP are produced
Electron Transport Chain
You are a large organism and need a lot of___ to keep you fueled
ATP
accumulates in your muscle cells, acid burns the cells,
causing you to cramp up & thus slowing down your activity
Lactic acid
used in baking, wine making and brewing industry
Yeast & some bacteria
production is used in cheese processing, buttermilk, sour cream, yogurt, sauerkraut, pickles.
Lactic Acid
The souring of dairy products is actually the production of lactic acid by____
anaerobic bacteria
Occurs in cytoplasm
Glycolysis
You are a large organism and need a lot of ATP to keep you fueled.
Muscle Fatigue
At times though, you may not be breathing correctly & therefore, are not taking in enough O2 to remain an aerobic organism.
muscle fatigue
During this time, your body (muscle cells) converts to anaerobic respiration to give you some ATP. Hey, 2 ATP are better than none!
muscle fatigue
