Photosynthesis
What energy source do plants use to perform photosynthesis?
sunlight
Who carries out cellular respiration?
plants and animals, producers and consumers
heterotrophs and autotrophs
What is fermentation?
An energy releasing processes that requires glucose, but no oxygen.
True or False: Plants produce carbon dioxide during photosynthesis
oxygen
What are the products of respiration?
Carbon dioxide, energy, water
How does photosynthesis benefit heterotrophs?
Heterotrophs cannot make their own food, so they must eat consumers or producers. These producers use photosynthesis and store some of the energy so it is passed to the heterotrophs.
What are the raw materials for respiration?
glucose and Oxygen
What type of fermentation occurs in yeast?
alcoholic
True or False: Photosynthesis and respiration form a cycle.
True
stomata
What enters plants through the stomata?
Carbon dioxide
What happens during Stage 1 of cellular respiration and where does it occur?
Glucose molecules are broken down into smaller molecules releasing a small amount of energy (2 ATP)
When would lactic acid fermentation take place?
a fast run
True or False:The raw materials for respiration are the opposite of the end products of photosynthesis.
False- same as
Where do animals get glucose for use in cellular respiration?
food
What are the products of photosynthesis?
glucose, Oxygen
What happens during Stage 2 of cellular respiration and where does it occur?
In the mitochondria, small molecules of glucose react with oxygen and produce water, carbon dioxide, and large amounts of energy (36 ATP)
Under which conditions does lactic acid fermentation occur?
If the body cannot take in oxygen fast enough, the muscles use fermentation to add to the energy without using oxygen.
When muscle cells run low on oxygen, lactic acid fermentation takes place.
true
What is the major difference between fermentation and cellular respiration?
Both are energy releasing processes, but fermentation requires no oxygen.
What is the photosynthesis equation?
6CO₂ + 6H₂O + Light Energy → C₆H₁₂O₆ + 6O₂
How are photosynthesis and cellular respiration opposite processes?
The products of photosynthesis (glucose and oxygen) are the reactants of cellular respiration. They form a cycle.
What are the end products of fermentation?
Carbon Dioxide, energy, lactic acid
Photosynthesis and respiration form a cycle that keeps the levels of water and carbon dioxide fairly constant in the atmophere.
oxygen
What is the equation for cellular respiration
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
