Cellular respiration
Where in the cell does cellular respiration take place?
mitochondria
Use the figure below to explain how carbon is cycled through the biosphere. SG#80
E.A liquid or gaseous fuel is oxidized, releasing carbon dioxide.
What is an autotroph? Give an example.
An autotroph is an organism that can produce its own food. Plants are autotrophs.
Use the figure below to explain how carbon is cycled through the biosphere. SG#80
C.Decomposers break down the remains of dead plants and animals, and release carbon dioxide through respiration.
Write the overall chemical equation for cellular respiration. Label the reactants and products. What is the energy source for cellular respiration?
C6H12O6 + O2 ------> CO2 + H2O + ATP. The reactants are oxygen and glucose. The products are ATP, CO2, and water. The energy source is glucose molecules.
Explain how photosynthesis and cellular respiration related. Think about how they both help to cycle matter within an ecosystem. Use the model below in your response. Identify A, B, C, and D in the figure. SG#74
Photosynthesis and cellular respiration are related because in photosynthesis, sunlight is given, water is absorbed, and carbon dioxide is taken in and it releases oxygen and sugars. Then, in cellular respiration, the organisms take that sugar and oxygen, and release ATP, the CO2 and water the plants need in order to photosynthesize.
Compare the amount of energy in the cellular respiration products compared to the cellular respiration reactants. Hint: Remember energy is released.
The amount of energy in the products is the same as the reactants because energy is released for ATP, but not destroyed. The Law of Conservation of Matter says that reactants and products must equal each other.
What is a heterotroph? Give an example.
A heterotroph is an organism that gets its food from plants and other organic substances. Humans and animals are heterotrophs.
Use the figure below to explain how carbon is cycled through the biosphere. SG#80
A.Cellular respiration releases carbon dioxide that is stored in the atmosphere.
In cellular respiration, what energy is coming out? How is that energy utilized?
ATP is coming out and it is utilized when an organism needs to use that energy to perform daily functions.
Use the figure below to explain how carbon is cycled through the biosphere. SG#80
B.Photosynthesis uses that stored carbon dioxide and turns it into oxygen and sugar.
Use the figure below to explain how carbon is cycled through the biosphere. SG#80
D.The pressure of the layers of sediment will result in the decomposed organism becoming a liquid over a period of millions of years. These liquids are fossil fuels such as: oil, coal and gas. The fossilization has produced fossil fuels which we burn, which results in the release of Carbon Dioxide
Use the figure below to explain how carbon is cycled through the biosphere. SG#80
F.If methane is leaked or given off from animals, CO2 levels increase.
Why is it important to convert the energy in glucose into the ATP molecules? Why do we need ATP?
It is important to convert the energy in glucose into the ATP molecules because energy is needed to survive. We need the ATP because It is the high-energy molecule that stores the energy we need to do just about everything we do.
In photosynthesis, what energy is going in? How is that energy utilized?
The energy from the sun/heat energy is going in and it is utilized by the plant taking it in to break the bonds of CO2 and H2O to make sugars and oxygen
Photosynthesis is ENDOTHERMIC, meaning that it requires input of ____/____ to occur. Whereas cellular respiration is EXOTHERMIC, meaning the _____ of energy occurs.
energy/heat output
