What is the balanced chemical equation for cellular respiration?
C6H12O6 (Glucose) + 6O2 (oxygen gas) --> 6CO2 (Carbon dioxide) + 6H2O (Water)+ ATP
What is the purpose of cellular respiration?
To break down sugar in the presence of oxygen to release energy in the form of atp
Which organelle does aerobic cellular respiration take place in?
Mitochondria
Cell respiration without any oxygen is known as
anaerobic respiration or fermentation
Where does glycolysis take place?
Cytoplasm
Glycolysis literally means
A process which sugar is partially broken down by cells in enzyme reactions that do need oxygen
What is the purpose of the Krebs/Citric acid cycle?
the main source of energy for cells and an important part of aerobic respiration.
Where in the mitochondria does the Electron transport chain take place?
inner membrane
What is the purpose of the electron transport chain
to transfer energy from the electron carriers to even more ATP molecules
How much ATP is released when glucose is broken down during aerobic cellular respiration
30-32 ATP
ADP stores energy in ATP in an _____ reaction
Endergonic
ATP releases energy in an ____ reaction
Hydrolysis
What is the difference between ATP and ADP?
ATP has three phosphate molecules and therefore more energy than ADP, which only has two phosphate molecules.
How are autotrophs and heterotrophs different from each other?
Autotrophs make their own food while heterotrophs rely on a different source
Why do organisms that have no oxygen die?
Oxygen is one of the most important sources for all living things
Photosynthesis and cellular respiration recycle these four molecules
carbon dioxide, water, oxygen and glucose.
What is the balanced chemical equation for photosynthesis?
6CO2 (carbon) +6H2O (water) →C6H12O6 (glucose) +6O2 (oxygen)
What is the purpose of photosynthesis?
to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel
Chlorophyll ______ green light and ________ red and blue light
reflects and absorb
Where in the chloroplasts do the light-dependent reactions take place?
thylakoid
What is the purpose of the Light-dependent reaction?
to make two molecules needed for the next stage of photosynthesis
What is the purpose of the Light independent reaction?
to assemble a molecule of glucose
Why do plants have different pigments?
so they can absorb energy from a wide range of wavelengths.
What is the source of energy for almost all living things on earth?
the sun
which three factors can impact a plant's rate of photosynthesis
light intensity, carbon dioxide concentration and temperature
which part of the plant does the most photosynthesis
Leaf because they have the most chloroplasts
What would happen to the rate of photosynthesis of a plant has no h2o or CO2
Plant will die
More oxygen from plants =
higher
Do plants perform cellular respiration?
Yes they do the energy released during cellular respiration gives the power to carry out the functions of the cells.
Why do plants in the dark die?
they will not have any food or nutrients
What is the first law of Thermodynamics?
energy in an isolated system is always conserved by changing from one form to another and it is neither created nor destroyed.
What is the second law of thermodynamics?
a system in which neither energy nor matter can enter or leave.
Energy _____ from a high energy source to uncontrollable entropy
flows
However, matter _____ between processes like photosynthesis and respiration
cycles
