Test 2 Flashcards
(36 cards)
Producers- are organisms that make their own food and organic matter from inorganic nutrients
Autotrophs (self feeders)
Consumers- can not make organic molecules from inorganic ones
Heterotrophs (other-feeders)
Sunlight energy=
Photons
Products of photosynthesis
Glucose(C6 H12 O6) and oxygen (O2)
Products of cellular respiration?
Carbon dioxide(CO2) and water (H2O)
Converts light energy into sugar
Photosynthesis
The chemical equation for photosynthesis
6CO2+6H2O+light energy➡️C6H12O8+6O2
Carbon dioxide+water+light energy➡️sugar+ oxygen
Plants aren’t the only autotrophs what are three others?
Kelp
Cyanobacteria
Other unicellular organisms
Algal blooms in lake Eire are caused by?
Farm and industrial run off
Home lawn run off
Algal blooms in Lake Erie result in________?
Anoxia
- oxygen depletion in water
- Fish move or die
- hurts economy
Where does photosynthesis occur?
Chloroplast
Light consist of _______ that contain energy
Photons
Photons turn into what in the thylakoid membranes?
An excited electron
__________ capture light energy
Such as?
Pigment molecules
Chlorophyll or carotenoids
Light reactions in a chloroplast.
Takes in light and water (inside the light reaction part it uses NADP+ and ADP)and converts it to ATP and NADPH. oxygen (O2) is a byproduct. (Light dependent)
Calvin cycle
Light independent reaction, enzymes use energy molecules like carbon dioxide, NADPH, and ATP to synthesize glucose and other organic molecules (sugar). Puts back in NADP+ and ADP out puts sugar
Why we need photosynthesis?
- all heterotrophs depend on it.
- we can’t make food energy on our own.
- “but I don’t eat my veggies” your food eats veggies.
Vegetarians are more efficient
It takes ___lb of corn to make ___lb of beef
4,1
Chemical formula for cellular respiration
C6H12O6+6O2➡️6CO2+6H2O+ATP
Glucose +oxygen➡️ carbon dioxide+ water+Energy
AROBIC energy harvesting of food molecules
Cellular respiration
Like chloroplast _______ has a double membrane
Mitochondria
Occurs when there is little to no oxygen available
Fermentation
These are high energy electron carriers.
NADH and FADH
Input and output of citric cycle
Input= acidic acid, ADP+P, 3 NAD+, FAD Output= 2 CO2, 2 ATP, 3 NADH, FADH2
