Photosynthesis and Respiration Flashcards
Module 1
What is photosynthesis?
A chemical reaction that converts light energy into chemical energy in the form of glucose.
What organisms photosynthesize?
Plants, algae, and some bacteria.
Where does photosynthesis take place?
In chloroplasts, an organelle found in plants.
What is chlorophyll?
A green pigment capable of absorbing light energy, found in chloroplasts.
What is the equation for photosynthesis?
Carbon dioxide + Water -> Glucose + Oxygen
What is carbon fixation?
The conversion of inorganic carbon into organic sugars that combine to form glucose.
What are the two main stages of photosynthesis?
- Light-dependant reactions
- Light-independant reactions
Where do light-dependant reactions take place?
The thylakoid membrane.
What happens in the light-dependent stage?
Chlorophyll absorbs light energy and converst it into chemical energy. In this stage, oxygen is release as a byproduct.
Where do light-independent reactions take place?
The stroma of the chloroplasts.
What happens in the light-independant stage?
Carbon fixation occurs. Inorganic carbon dioxide is converted into organic suger that combine to form glucose.
What are inorganic molecules?
Molecules that naturally occur in nature without being produced by an organism.
What are organic molecules?
Chemicals produced by organisms.
What is cellular respiration?
A process undergone by all organisms to gain useable energy in the form of adenosine triphosphate (ATP).
What type of respiration to animals and plants use to gain most of their energy?
Aerobic respiration.
