cell respiration Flashcards
Equation of cellular respiration
C6 H12O6+O2—- CO2+H2O+ Energy
What are the reactants and products of cellular respiration?
Reactants- oxygen & glucose Products- water, carbon dioxide, & Energy
True or false
Cellular respiration takes place in both plants and animals
True
Which organelle in a plant or animal cell is the primary site for ATP production?
Mitochondria
Where do plant cells obtain their glucose for cell respiration?
Through the process of photosynthesis
Is cellular respiration breaking glucose or making glucose?
breaking glucose
Is cellular respiration storing energy or releasing energy?
releasing energy
What is the energy source of aerobic and anaerobic respiration?
Glucose
What role does oxygen play in cellular respiration
Helps to produce H2O
Where in a plant or animal cells do aerobic (A) and anaerobic (B) respiration occur?
A: Mitochondria B: Cytoplasm
How does cellular respiration maintain homeostasis at a cellular level?
Maintaining oxygen and CO2 by eating food
What happens to carbon dioxide produced by cellular respiration?
It is recycled back into the system by plants by the process of photosynthesis
How is the chemical energy in glucose similar to money in a saving account?
We save up ATPs that we can use later like saving money to use later.
How much ATP energy do we get out of one molecule of glucose?
36 ATPs
What does it mean if a process is anaerobic? Anaerobic does not need oxygen. Which part of cellular respiration is anaerobic?
Glycolysis is the part of cellular respiration that is anaerobic also goes in fermentation.
Name 2 types of fermentation
Lactic-acid Fermentation(follows glycolysis)
- Turns pyruvate into lactic acid
- Occurs in skeletal muscle during anaerobic exercise
- Used to make cheese,yogurt, sour cream
Alcoholic Fermentation
- Yeast and bacteria use this process
- Use pyruvate to make ethyl alcohol and carbon dioxide
- Use to make breads, beers, and wines
How do organisms generate energy when oxygen is not available?
Anaerobic respiration (glycolysis and fermentation)
Why do muscles of runners sometimes produce lactic acid
Go into Anaerobic respiration bc not enough oxygen
Why do runners breathe heavily after a sprint race?
Could not take in enough oxygen while running
Bread rises as a result of yeast fermentation. How might fermentation causes bread to rise?
fermentation gives off Carbon Dioxide and alcohol. Alcohol evaporates
What do fermentation and a detour that drives must use when roads are closed have in common?
Back up system, when there is no other way
Produces ethyl alcohol
alcoholic
Produces carbon dioxide
alcoholic
Produces 2 ATP
alcoholic and lactic acid
Occurs in muscle cells
lactic acid
Occurs in yeast and bacteria cells
alcoholic
Used for making dairy products
lactic acid
Used for making wine and beer
alcoholic
No oxygen is required
Lactic Acid and Alcoholic
P+C where does it take place
P: chloroplast
C: mitochondria
P+C When does it take place
P: present of life
C: All the time
P+C reactants
P: CO2+H2O
C: C6 H12O6+O2
P+C products
P: C6 H12O6+O2
C:CO2+H2O
P+C energy source
P: sunlight
C: glucose
P+C energy result
P: glucose
C: 36 ATP
What do autotrophs make that heterotrophs need
oxygen and glucose
What do heterotrophs make that autotrophs need
carbon dioxide and water
3 examples of autotrophs
trees, flowers, plants,algae, some bacteria
3 examples of heterotrophs
fungus, animals, humans
Which process removes carbon dioxide from the atmosphere
photosynthesis
Which process adds CO2 to the atmosphere
cell respiration
Which process adds oxygen to the atmosphere
photosynthesis
Which process removes O2 from the atmosphere
cell respiration
Which process is making glucose
photosynthesis
Which process is breaking glucose down for energy
Cell respiration
important note
everyone goes through anaerobic respiration first, then through aerobic respiration to break down the glucose
