Lab Exam 2 Review

Review for Lab Exam 2 (Final)

QuestionAnswer
What is the formula for aerobic respiration? C6H12O2 + 6O2 -> 6H2O + 30-32 ATP (Glucose and oxygen are converted into carbon dioxide and thirty to thirty two ATP are added to the end of the equation completing respiration.
What is the formula for anaerobic respiration? (Alchol fermentaion) C6H12O6 -> 2CO2 + 2 ATP (Glucose is converted into carbon dioxide and two ATP are added to the end of the equation completing respiration.
What end product in the equation for aerobic respiration contains the carbon atoms from glucose? Carbon dioxide
What end product in the equation for aerobic respiration contains the oxygen atoms from glucose? Carbon dioxide
What end product in the equation for aerobic respiration contains the hydrogen atoms from glucose? Water
What end product in the equation for aerobic respiration contains the energy stored in the bonds of the glucose? ATP
How do plants obtain glucose for cellular respiration? Plants convert light energy in a process known as photosynthesis. This process also allows plants to conduct the Calvin Cycle which is how plants obtain their glucose for cellular respiration.
How do herbivores obtain glucose for cellular respiration? Herbivores eat plants (autotrophs) to obtain glucose for cellular respiration.
How do carnivores obtain glucose for cellular respiration? Carnivores eat plants (autotrophs) like herbivores, but will also obtain glucose from other sources like meat such as steak for cellular respiration.
How many ATP are produced by aerobic respiration? 30 to 32
How many ATP are produced by anaerobic respiration? 2
Why is alcohol fermentation beneficial to some bacteria? Some bacteria are only able to survive in oxygen deficient environments provided by the alcohol fermentation process.
Do plants ever give off CO2? If so, when and where does it come from? Plants give off CO2 most often during the nighttime when there is no light energy for photosynthesis to take place. CO2 comes from the cellular respiration process.
Would you expect a color change occur if you blew into a test tube containing phenol red? Why or why not? Yes, because phenol red is a pH indicator and would react to an element (which one?) in my breath as I exhaled.
What is the equation for photosynthesis? 6CO2 + 6H2O -> C6H12O6 + 6O2
When a section of a leaf stains blue-black, what does that mean? Starch is present on that section of the leaf.
When a section of a leaf fails to stain blue-black, what does that mean? Starch is no longer present.
For a light-grown leaf, is there a difference in the staining of the covered vs. uncovered sections? Explain. Lugol's solution reacts with starch, which means that the covered section of the leaf should be found to no longer have starch present while the uncovered section will still have starch present.
In order for photosynthesis to occur, what must be present as the energy source? Light
In order for photosynthesis to occur, what must be present as the carbon source? Carbon dioxide
In order for photosynthesis to occur, what must be present as the electron donor? Water
In order for photosynthesis to occur, what must be present for the absorption of light energy? Pigment
Why must grow lights for house plants never be green? The chlorophyll in plants absorbs blue and red light which are both near two ends of the visible spectrum and make up the green in leaves of the house plants. Green lights on these plants would not produce green leaves!
How are plants that have been kept in the dark for a week still able to conduct cellular respiration? Plants kept in the dark for a week are still able to conduct cellular respiration by storing glucose as starch which allows them to continue conducting cellular respiration.
What is the purpose of light-dependent reactions and where do they occur in the chloroplast? These reactions use light energy to pass on excited electrons to NADP+, reducting it to NADPH and occurs in the grana of the chloroplast.
What is the purpose of light-independent reactions and where do they occur in the chloroplast? These reactions use light energy to oxidize water molecules, producing electrons, protons and oxygen and occurs in the thylakoid membrane of the chloroplast.
What are the stages of mitosis, in order? Prophase, Prometaphase, Metaphase, Anaphase, Telophase
What is the first stage of mitosis? Prophase: condensing chromosomes become viible; spindle fibers appear
What is the second stage of mitosis? Prometaphase: nuclear envelope disappears; spindle fibers attach to kinetochores
What is the third stage of mitosis? Metaphase: sister chromatids line up along the equator of the cell; sister chromatids are attached to the spindle fibers
What is the fourth stage of mitosis? Anaphase: the sister chromatids separate (now called chromosomes again) and move towards the opposite poles of the cell
What is the fifth stage of mitosis? Telophase: the chromosomes have reached the opposite poles of the cell and begin to expand; spindle disappears; the nuclear envelope reforms
Which type of cell division results in diploid cells? Mitosis
Which type of cell division results in cells with identical genetic composition? Mitosis
During which phase of mitosis does the nuclear envelope disappear? Prometaphase
During which phase of mitosis are chromosomes first visible? Prophase
During which phase of mitosis does the nuclear envelope reform? Telophase
During which phase of mitosis do chromosomes move towards opposite poles of the cell? Anaphase
During which phase of mitosis do spindle fibers appear? Prophase
During which phase of mitosis do sister chromatids line up along the equator of the cell? Metaphase
What are two differences between mitosis in animal and plant cells? Animal cells contain centrioles which form to organize the spindle. Plant cells do not have centrioles. Plants form a cell plate at which a new cell wall forms while animal cells begin cytokinesis with a furrowing of the plasma membrane.
Why is crossing over observed in meiosis but not mitosis? Homologs pair up during meiosis allowing them to physically interact and cross over. IN mitosis, homologs do not pair up; they act separately an do not necessarily come close to one another.
How does independent assortment lead to genetic diversity in mitosis? Each chromosome behaves independently of its homolog and its two chromatids are sent to opposite poles during Anaphase.
How many chromatids are present in a cell with 16 chromosomes undergoing mitosis during prophase? 32
How many daughter chromosomes are present in a cell with 16 chromosomes undergoing mitosis during anaphase? 32
How many chromosomes does each daughter cell have in a cell with 16 chromosomes undergoing mitosis after cytokinesis? 16
When would you expect to find the greatest amount of mitotic activity in the life of an organism? During the embryo and developmental stage (pregnancy in humans and animals) when new life is forming.
What is a phenotype? Physical trait
What is a genotype? Combination of alleles
