Chapter 10 Flashcards
Plant Metabolism
Metabolism
the sum of all the interrelated biochemical processes that take place in a living organism
Enzymes
Proteins that speed up chemical reactions in cells without being used up in the reactions
The process in which enzymes help form chemical bonds in order to build molecules
Anabolism
Enzymes also break chemical bonds through the process of…
Catabolism
Most reactions of photosynthesis are…
ANABOLIC, because they involve the construction of molecules that are stored for energy.
Reactions in cellular respiration (respiration) are…
CATABOLIC, because they release energy held in chemical bonds
The processes of both photosynthesis and respiration include many _________ - _________ reactions
Oxidation-Reduction Reactions
Oxidation
The loss of one or more electrons, involves removal of electrons from a compound.
(LEO)
Reduction
Gain of one or more electrons, involves the addition of electrons to a compound.

ATP
Adenosine Triphosphate, Energy storing molecules
6CO2 + 6H2O + light energy = C6H12O6 + 6O2.
photosynthesis equation.
6 Carbon Dioxide + 6 Water +light energy= Sugar and 6 Oxygen
Photorespiration
considered to be a wasteful process that uses oxygen and releases carbon dioxide
Photooxidation
“bleaching”, involves the destruction of chloroplasts by light
All chlorophyll molecules contain an atom of
Magnesium (Mg)
