Cellular Metabolism Chapters 10, 11,12 Flashcards
Where is energy stored in atp and how is it released?
Stored in chemical bonds
Added or released by adding or breaking bonds to phosphate group
Process used to break down glucose to create atp?
Cellular respiration
T/F: plant respiration is the opposite of cellular respiration bc plants take in co2 and expel o2 while animals breathe in o2 and exhale co2
False
What part of the plant cell is used to take in atmospheric carbon dioxide?
The stoma
Where are stomata located
On leaf surfaces and stems, mostly on undersides
What is another function of stomata other than gas exchange for photosynthesis?
Controlling the rate of transpiration to conserve water (e.g. Desert plants)
Chemical equation for photosynthesis
6CO2+6H2O in the presence of light energy = C6H12O6+6O2
Chem equation for respiration
C6H12O6+6O2=6CO2+6H2O+energy (atp)
Are the equations for photosynthesis and respiration opposites?
Yes except photosynthesis has light energy and respiration had chemical energy
Two reactions of photosynthesis?
Light reactions
Light independent reactions(calvin cycle)
In what part of the chloroplast do light reactions occur?
The thylakoid
Where in the chloroplast does the calvin cycle occur?
In the stroma
Why are plants green?
Their primary plant pigment, chlorophyll A, absorbs red, blue, and yellow light but reflects green
What is the role of plant pigments in photosynthesis?
They absorb light energy that is used to excite electrons in the light reactions
What molecule is used to store energy in living things?
ATP (adenosine triphosphate)
