Flashcards in Test 2 Deck (36):
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
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
The chemical equation for photosynthesis
Carbon dioxide+water+light energy➡️sugar+ oxygen
Plants aren’t the only autotrophs what are three others?
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________?
-oxygen depletion in water
-Fish move or die
Where does photosynthesis occur?
Light consist of _______ that contain energy
Photons turn into what in the thylakoid membranes?
An excited electron
__________ capture light energy
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)
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
Chemical formula for cellular respiration
Glucose +oxygen➡️ carbon dioxide+ water+Energy
AROBIC energy harvesting of food molecules
Like chloroplast _______ has a double membrane
Occurs when there is little to no oxygen available
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
What does each of these ➡️ mean
1st one transcription
2nd one translation
Makes a copy of the DNA, is the first in the RNA group, happens inside nucleons
2nd in the RNA group, translates, brings appropriate amino acid to RRNA, happens in the rough ER
A group of three nucleotides like T,A,C
Start_____ and stop ____ tell it when to start and stop transcribing
The DNA sequence where RNA start to attach is called the
In bacteria the sequence signaling the end of transcription is the
The stretch of DNA that is transcribed is called a
DNA= A=_, C=_
RNA= A=_, C=_
DNA= T, G
The organizer slash lock of the RNA, it happens last in the rna group, allows it to bond to mrna
Most abundant enzyme on earth, turns carbons into glucose
a sequence of three nucleotides in a region of transfer RNA that recognizes a complementary coding triplet of nucleotides in messenger RNA during translation by the ribosomes.
