The pure “fire air” consumed by a burning candle in a sealed glass jar, or by a mouse during aerobic respiration (in experiments conducted by Joseph Priestley), contains which of the following elements?
hydrogen and carbon (derived from the C6H12O6 produced by plants during photosynthesis)
carbon and oxygen (derived from the CO2 consumed by plants during photosynthesis)
carbon only (derived from the C6H12O6 produced by plants during photosynthesis)
hydrogen only (derived from the H2O produced by plants during photosynthesis)
oxygen only (derived from the O2 produced by plants during photosynthesis)
Statement A: The flow of matter across the earth’s subsystems involves the transformation of matter into energy.
Statement B: The breakdown of glucose molecule into H2O and H2O in the process of cellular respiration corresponds to the formation of a chemical form of energy adenosine triphosphate
Both statements A and B are correct
Statement A is correct, statement B is incorrect.
Statement A is incorrect, statement B is correct
Neither statement A nor statement B is correct.
The law of conservation of matter states that no matter on earth can be created or destroyed. Using the following equation: 6H2O + 6CO2 + Sunlight—> C6H12O6 + 6O2, explain how the process of photosynthesis is an example of this.

- Your science teacher says that matter is conserved in the process of cellular respiration. What does he mean by that? (a) None of the atoms in the food that we eat are destroyed during the process, and no new atoms are created in the formation of carbon dioxide, water and ATP (b) None of the molecules in the food are destroyed during the process, and no new molecules are created after the reaction between glucose and oxygen (c) Molecules in our food are destroyed, and new molecules, of carbon dioxide, water and ATP are created (d) None of the matter, whether solid, liquid, or gas, changes states during the process.arrow_forwardCell respiration and photosynthesis are distinct metabolic processes that take place in the mitochondrion and chloroplast, respectively. While these two processes are separate, they share things in common. When one looks at the overall equations for cell respiration and photosynthesis, one sees how they are near opposites in terms of the starting and ending materials. In 300-400 words, describe this “near opposite” relationship between cell respiration and photosynthesis. What are the starting and ending materials in each process, and what kind of energy transformation is taking place?arrow_forwardThe movement of energy between living organisms is a matter of atoms, molecules and compounds being built into larger molecules or being broke into smaller ones. Reviewing the two equations for energy transference, which one is building energy? 6CO2 + 6H2O + energy --------> C6H12O6 + 6O2 C6H12O6 + 6O2 ---------> 6CO2 + 6H2O + energyarrow_forward
- What molecule is considered as a by-product of photosynthesis which is used by mammals to breathe? C6H12O6 CO2 H2O O2arrow_forwardWhich of the following statements is not correct? a. Energy cannot be created or destroyed. b. Energy cannot change from one form to another. c. Energy tends to disperse spontaneously. d. Energy can be transferred.arrow_forwardWhere Do the O Atoms in Organisms Come From? Name three principal inorganic sources of oxygen atoms that are commonly available in the inanimate environment and readily accessible to the biosphere.arrow_forward
- Which of the summary statements below describes the results of the following reaction? C6H1206 + 6 O2 → 6 CO2 + 6 H2O + Energy O C6H1206 is oxidized and O2 is reduced. O 02 is oxidized and H20 is reduced. O CO2 is reduced and 02 is oxidized. O 02 is reduced and CO2 is oxidized.arrow_forwardPhotosynthesis is defined as the chemical process, wherein carbon dioxide in the presence of water and radiant energy gets converted to glucose (chemical energy), giving out oxygen as byproducts. In the equation, the combining reactants and resulting products are expressed along with their respective numbers of molecules. Putting this in a simplified formula, the following equation represents this process. CO2 + H2O + Light energy → C6H12O6 + O2 Considering this equation, how plant lovers (plantitos and plantitas) able to cultivate their plants?arrow_forwardWhere does the following reaction take place in a cell? Glucose + O2 ----> CO2 + H2O + ATP a nucleus b chloroplast c cytoplasm d mitochondriaarrow_forward
- (a) It can be argued that, if life were to exist elsewhere in the universe, it would require some process like photosynthesis. Why is this argument reasonable? (b) If the starship Enterprise were to land on a distant planet and find no measurable oxygen in the atmosphere, could the crew conclude that photosynthesis is not taking place?arrow_forwardRadioactive isotopes are routinely used to investigate processes in living things. In 1941, biologists exposed photosynthesizing cells to water containing a heavy oxygen isotope, designated 18-O. The labelled isotope appears in the oxygen gas released in photosynthesis, demonstrating that the oxygen came from water. Explain where the 18-O would have ended up if the researchers had used 18-O-labelled carbon dioxide.arrow_forwardPhotosystem I (in the green sulfur bacteria) uses either dim underwater volcanic light or dim sunlight to strip away electrons (and protons) from which of the following substrate molecules? C6H12O6, H2O, and CO2 only CO2 only C6H12O6, and H2S only H2S only CO2 and H2O onlyarrow_forward
