100
Can energy be created or destroyed?
No, energy cannot be created nor destroyed but can be converted from one form to another.
100
Where does photosynthesis occur in the cell?
The chloroplast
100
Where does cellular respiration take place in the cell?
In the mitochondria

What is the difference between catabolic and anabolic pathways?
Catabolic pathways release energy by breaking down complex molecules into simpler compounds AND Anabolic pathways consume energy to build complex molecules from simpler ones
200
What is the equation for photosynthesis?
Sunlight + Carbon dioxide + Water --> glucose + Oxygen
200
What is needed for cellular respiration to occur, and what is released?
Glucose + oxygen --> ATP + carbon dioxide + water
300
What does the first law of thermodynamics state?
It states that the energy of the universe is constant, meaning that energy can be transferred/transformed but cannot be created/destroyed.
300
In what type of animal is photosynthesis practiced?
Autotrophs use the process of photosynthesis to convert water, carbon dioxide, and solar energy into sugars and oxygen.

What is free energy? what equation is used?
Free energy: is energy that can do work when temperature and pressure are uniform, as in a living cell. The change in free energy (∆G) during a process is related to the change in enthalpy, or change in total energy (∆H), change in entropy (∆S), and temperature in Kelvin (T): ∆G = ∆H – T∆S

What is the purpose of the chloroplast's double-membrane?
Chloroplasts have a double-membrane that creates a compartmentalized structure that allows cells to capture energy available in sunlight & converts it to chemical bond energy via photosynthesis
400
Why does the mitochondria have a double-membrane?
It allows for compartmentalization of reactions. The outer membrane is smooth and the inner membrane is highly convoluted, forming folds (cristae) which contain enzymes important for ATP production.
