Photosynthesis
What are the inputs (reactants) of photosynthesis?
Inputs: light, carbon dioxide, and water.
Identify what two inputs are needed for cellular respiration.
Oxygen and glucose
How are glucose and fructose similar?
Both are made of carbon-oxygen rings.
In what way(s) is ATP like a fully charged battery?
ATP is like a charged battery because it stores energy and it powers many processes.
Why was sodium bicarbonate applied to the spinach leaves in the investigating light sources lab?
Sodium bicarbonate is used as a source of carbon dioxide gas, which is a necessary reactant of photosynthesis.
Where in plant cells does photosynthesis take place?
Chloroplast
Another term for "ATP" is _____.
Chemical energy
How are glucose and fructose different?
The ring in fructose is smaller, containing only four carbons. This makes the angles between the ring atoms smaller.
What is Glycolysis?
Glycolysis is an anaerobic process that breaks glucose into two three carbon-carbon molecules called pyruvate.
Where in the cell does cellular respiration take place?
Mitochondrion
What is the photosynthesis equation?
6CO2 + 6H20 + light → C6H12O6 + 6O2
True OR False: Only animals can perform cellular respiration.
False: Some plants can do cellular respiration in the dark.
Which light source is best for optimizing oxygen production in spinach leaves? WHY?
Typically, red and blue light result in higher rates of photosynthesis than green light. Green light is reflected by chloroplasts, giving plants their green color.
What happens to the sugars that are made during photosynthesis?
They can be used for cellular respiration.
When photosynthetic organisms use energy from the sun to convert carbon dioxide and water into simple sugars, such as glucose, what happens to each molecule?
Chemical bonds in both molecules are broken and new compounds are made when the atoms form new bonds.
True OR False: Photosynthesis is an aerobic process.
True: Photosynthesis requires oxygen.
What is the cellular respiration equation?
C6H12O6 + 6O2 → → → 6CO2 + 6H2O + heat + ATP
In your snail model, why was the jar sealed and how did it affect the organisms living in the jar?
The celery provided the snail with oxygen and glucose and the snail provided the celery with CO2 and water. They kept each other alive.
What do chloroplasts and mitochondria have in common?
They are both organelles where major processes take place.
What process in the mitochondria provides the electron transport chain in cellular respiration with the energy it needs to function?
Krebs cycle (provides NADH, FADH2, and ATP molecules).
ATP (adenosine triphosphate) stores energy in the bonds between its __________.
3 phosphate (bonds)
Explain why the relationship between photosynthesis and cellular respiration is usually described as a cycle.
the inputs of one process are the outputs of the other process.
How does the anthrosphere interact with your snail model?
Humans provide heat, water, and love to the snails.
There are three steps in cellular respiration. List them in order.
Glycolysis --> Krebs Cycle --> Electron Transport Chain
Explain how carbon-based rings and chains can form very large molecules. Hint: think about our modeling biochemical compounds lab.
Breaking/forming oxygen and carbon bonds
