What substances are recycled during photosynthesis and respiration? Water, Oxygen,
What is one component of photosynthesis that is not recycled and must be constantly available? Sunlight
Are chloroplasts found in plant cells? Yes

the higher the line in the light and energy absorbtion graph the... more absorbed a color is
if something doesn't absorb a color, then... it reflects it
What removes carbon dioxide from the air? Photosynthesis
Why is Fermentation important? because it allows glycolysis to continue making ATP when Oxygen is unavailable for cellular respiration
Fermentation removes _______ from NADH and recycles NAD+ to glycolysis electrons
Fermentation takes place in your muscle cells during ___________, when not enough Oxygen is available hard exercise
Fermentation is an... anarobic process because it occurs without Oxygen

what does the term fermentation mean? "to bubble"
Bubbles of ______ are produced in alcoholic fermentation. carbon dioxide
Lactic acid is the three-carbon ______ of lactic acid fermentation. waste product
Lactic acid causes a burning feeling in your ______ during exercise. muscles
What process occurs in all eukaryotes? Cellular Respiration
BEFORE the Calvin Cycle, what energy molecules are used to power it? ATP and NADPH
What is the difference between ATP and ADP? ATP has 3 phosphates, while ADP has 2, which means it has more energy than ADP
Which molecule has more energy: NADPH or NADP+ NADPH
AFTER the light independent reaction, what energy molecules are released? ADP and NADP+
Where does the Light DEPENDENT Reaction occur? Thylakoid Membrane inside the CHLOROPLAST
Where does the Light INDEPENDENT Reaction occur? Stroma of the Chloroplast
Where does Glycolysis take place? Cytoplasm
What 2 molecules are made from Glycolysis? Pyruvate
In the aerobic environments, what process will the products of glycolysis move into first? Krebs Cycle
In an anaerobic environment, what process will the products of Glycolysis move into? Fermentation
Where does the Krebs Cycle take place? Mitochondrial matrix
What are the 2 types of Fermentation? Alcoholic Fermentation and Lactic Acid Fermentation
What is another name for the Krebs Cycle? Citric Acid Cycle
What is cellular respiration? makes ATP by breaking down sugars and other carbon based molecules
Anaerobic Respiration occurs in three phases: Glycolysis, Krebs Cycle, and Electric Transport Chain
Glycolysis breaks down______ into 2 ________ and releases __ _____ Glycolysis breaks down glucose into 2 pyruvate to release 2 ATP
define Krebs Cycle... breaks down pyruvate through reactions producing electron carrier compounds, ATP and CO2
define Electron Transport Chain uses high electron carriers from Krebs cycle to generate ATP
define Fermentation anaerobic respiration of pyruvate
What organism does alcoholic fermentation occur in? plant and bacteria cells
What organism does lactic acid occur in? animals
What processes doesn't occur in the mitochondria? glycolysis (cytoplasm) and both fermentations (cytoplasm)
What process produces Ethanol? alcoholic fermentation
What processes require pyruvate? Krebs cycle, alcoholic fermentation and lactic acid fermentation
which process produces FADH2 Krebs Cycle
What processes produce NADH? glycolysis and Krebs
which process require glucose? glycolysis
which processes produce ATP? glycolysis, Krebs cycle, and ETC
which process produces the most ATP? electron transport chain
what process(es) produce lactic acid? lactic acid fermentation
which processes require oxygen? Krebs cycle and ETC
which process(es) produce pyruvate? glycolysis
which processes occur in the mitochondria? Krebs cycle and the ETC
how does the byproduct of cellular respiration used by yeast to make useful in the process of making bread? CO2 that is produced helps bread rise
explain how root cell get the energy the plant need to live, even though they don't contain chloroplasts? the roots draw in water, a key feature needed for photosynthesis
what was the independent variable in the lab observing photosynthesis with the blue solution? the amount of light
what was the dependent variable in the lab observing photosynthesis with the blue solution? the amount of CO2
what was the control group in the lab observing photosynthesis with the blue solution? the test tube with no plant
if the blue solution turns green, like in the lab, what has taken place? photosynthesis
what occurred when the green colored blue-solution turned back to blue? photosynthesis occurred, causing the CO2 from the solution to go into the plant
what is the line in the rap song that explained Glycolysis? Glycolysis....come on sugar, come on sugar, for the break down...for the break down...
what is the difference between anaerobic and aerobic respiration? anaerobic respiration means that there's no oxygen involved, and aerobic respiration is where oxygen is involved
where does the Krebs cycle take place? the mitochondrial matrix
where is the ETC located? in the inner membrane of the mitochondria
how many ATP does the ETC produce? 32-34 ATP
what is the chemical equation for cellular respiration? C6H12O6+6O2--->6CO2+6H20+36-38 ATP
is there light energy present in cellular respiration? no, it was converted to sugar in photosynthesis
what is located freely in the mitochondrial matrix enzymes
glycolysis yields how many net ATP? 2 ATP, because it goes up from 2 to 4 ATP
what is the first step of glycolysis? the 2 ATP molecules are used to energize a glucose molecule. The glucose molecule is split into two 3-carbon molecules
what is the second step of glycolyis? energized electrons from the 3-carbon molecules are transferred to molecules of NAD+. A series of reactions converts the 3-carbon molecules to pyruvate which enters cellular respiration
if no oxygen is involved after glycolysis, it goes to the _____. if oxygen is involved, then it goes to ________. no oxygen= fermentation and oxygen = Krebs cycle
Krebs cycle produces large quantities of... electron carriers like 8 NADH and 2 FADH2 that go to the ETC
step 1 of the Krebs cycle? pyruvate is broken down
step 2 of the Krebs cycle Coenzyme A bonds to the 2-carbon molecule. This intermediate molecule enters the Krebs cycle
step 3 of the Krebs cycle citric acid is formed (hence the nickname)
step 4 of Krebs cycle Citric acid is broken down and NADPH is made
step 5 of Krebs cycle 5-carbon molecule is broken down. NADH and ATP are made
step 6 of the Krebs cycle 4 carbon molecule is rearranged. NADH and FADH2 are formed.
what are the products of 1 pyruvate molecule? CO2 given off as a waste product, ATP, NADH goes to ETC, FADH2 goes to ETC
step 1 of the ETC H+ and E- are removed from NADH and FADH2
step 2 of ETC hydrogen ions are transported across the membrane
step 3 of the ETC ADP is changed into ATP when hydrogen ions flow through ATP synthase
step 4 of ETC water is formed when oxygen picks up electrons and hydrogen ions
what is the final electron acceptor in the ETC? Oxygen
what powers the proton pump? the building of the proton gradient (concentration gradient)
Chemiosmosis is... the diffusion of ions across the membrane
the products of glycolysis are... 2 NADH, 2 ATP and 2 pyruvate
the products of Krebs... 2 ATP, 8 NADH, 2 FADH2, AND 6CO2
the products of the ETC 6H2O, 32-34 ATP
how does the products from photosynthesis move from the chloroplast to the mitochondria? the chloroplast pushes out the organic molecules and oxygen, it gets "stamped" (which tells it where to go), glycolysis occurs in the cytoplasm, and then it goes to the mitochondria if it needs oxygen, or it stays and fermentation occurs
