What is the formula for photosynthesis?
6CO2 + 12H2O -> C6H12O6+6O2
What is the formula for cellular respiration?
C6 H12 O6+ 6O2->6CO2 + 6H2O + ATP
In what organelle does photosynthesis occur
Chloroplast
Which layers of cells in the leaf contain chloroplast
palisade and spongy mesopylie
Which layer had greatest concentration of chloroplast
palisade mesophyllie
What gas is required for photosynthesis?
CO2
What gas is released in photosynthesis?
O2
Which structures in the lower epidermis of the leaf allows CO2 to enter the leaf in exit O2
Stomata
In addition to CO2, what else is required for photosynthesis
sunlight
What are the three phases of cellular respiration
glyolysis, krebs, ETC
Where does cellular reparation begin in all types of cells?
cytoplasm
In what organelle for eukaryotes does cellular respiration primarily occur
mitochondria
What handles the steps of the Krebs cycle and ETC in prokaryotes
plasma membrane
What product of photosynthesis is metabolize in the steps of cellular respiration?
glucose
What organic compound do all cells produce in the metabolism of glucose?
ATP
Define photosynthesis
The most important biological process on earth
– Liberates oxygen
– Fulfills energy requirements
An energy-capturing process by which sunlight is converted to chemical energy to
synthesize carbohydrates.
plants’ way of making their engey and food
Define cellular respiration
A metabolic process whereby the utilization of oxygen and the breakdown of glucose yields
chemical energy in the form of ATP.
What is the theory of endosymbiosis
it is proposed that incorporating photosynthetic bacteria into larger cells may have led to the eventual development of the chloroplast organelle.
Evidence suggest that both mitochondria and chloroplast were at one
time, independent prokaryotes.
what are the two phases of photosynthesis and the differences
Light-dependent & Light independent
I. Light Dependent Reactions
a. Occurs on the thylakoid membrane of the chloroplast
b. Raw Materials
– Sunlight (absorbed by pigments)
– Water (from soil to roots)
c. Products
– ATP
– NADPH
– O
₂ (diffuses out through stomata)
II. Light Independent Reactions
a. Occurs in the stroma of the chloroplast
b. Raw Materials
– Carbon dioxide (diffuses in through stomata)
– ATP
– NADPH
c. Products
– Glucose
whart are classifed as hetrotrophs
Heterotrophs (consumers, Hetero=different)
– Herbivores
– Carnivores
– Omnivores
– Decomposers
what are classified as autotrophs
Autotrophs (producers, Auto=Self)
– Plants
– Algae
– Protists (euglena)
– Prokaryotes (cyanobacteria)
