I need help with this question:
Question 10
The balanced chemical equation for aerobic respiration is best represented by
A. C6H12O6+ 6O2 --> 6CO2 +6H2O + 30-32ATP
B. 6CO2 + 6H2O --> C6H12O6 +6O2
C. C6H12O6 + 6CO2 --> 6O2 + 6H2O
D. C6H12O6 + 6O2 + 30-32ATP + 30-32 Pi --> 6CO2 + 6H2O + 30-32ATP

    I need help with another question:
    Question 17
    What is the difference between C3, C4 and CAM plants?
    A. Unlike C3 and C4 plants, CAM plants, such as cactus, absorb carbon dioxide (CO2) during the day.
    B. C4 plants immediately integrate CO2 into a 3-carbon compound, whereas C3 and CAM plants initially integrate CO2 into a 4-carbon compound.
    C. C3 plants absorb more CO2 during the day, whereas C4 and CAM plants absorb more CO2 at night.
    D. CAM plants are suited to temperate climates, C3 plants are suited to dry environments and C4 plants are suited to marine environments.

      I have got yet another question:
      So I have been getting this question a few times in exams and the answers vary from company exam to company exam. What can I expect VCAA to want as an answer for this?
      Name the organelles of the cell involves in the production, transport, modification, and eventual secretion of the (protein) from the cell.
      Or
      Identify the sequence of organelles that is responsible for the production and secretion if (protein name).

        In our current study design you are not required to know the balanced equations for aerobic respiration and photosynthesis. All we need to know is the amount of ATP from each step in cellular respiration and the overall output (30 or 32ATP.
        In the previous study design you did have to know the balanced equation so you might come across questions like this but for this year you are not required to know the balanced equation 🙂

            I am not sure if this question is correct. I have completed the same question before on a practise exam but the first option was different:
            Question 17
            What is the difference between C3, C4 and CAM plants?
            A. Unlike C3 and C4 plants, CAM plants, such as cactus, absorb carbon dioxide (CO2) at night.
            B. C4 plants immediately integrate CO2 into a 3-carbon compound, whereas C3 and CAM plants
            initially integrate CO2 into a 4-carbon compound.
            C. C3 plants absorb more CO2 during the day, whereas C4 and CAM plants absorb more CO2 at night.
            D. CAM plants are suited to temperate climates, C3 plants are suited to dry environments and C4 plants
            are suited to marine environments

            This would make option A correct as CAM plants have the adaptation to absorb CO2 during the night to separate the light dependent and light independent stage by time. I am not sure what happened with the question on your end, maybe double check your question or look at where it is originally from?

                According to the Edrolo textbook these are the organelles you need to know for the direct production, transport, modification and eventual secretion of a protein:

                1. Ribosome - site of protein synthesis
                2. Rough Endoplasmic Reticulum - involved in initial folding of protein and transport to Golgi Body
                3. Transport Vesicle - transports protein to Golgi body.
                4. Golgi Body - Modifies proteins and then packages them into vesicles.
                5. Secretory Vesicle - Transports proteins around the cell and fuses with plasma membrane to secrete proteins into the extracellular environment.

                There are other organelles indirectly required for this process like mitochondria that produces ATP for the process but since it is not directly involved you are not required to write this is your answer. Hope this helps! 🙂

                    Yea i looked over at it and I am pretty sure it says during the day, which is weird. Mistake maybe?
                    Which practise exam have you done it on?
                    Mine was from NEAP

                      I have yet ANOTHER question lol:
                      Which one of the following would be a good source of biomass for the process of ethanol production?
                      A. Animal manure
                      B. Bacteria cultures
                      C. Yeast cultures
                      D. Wood pulp
                      I put C because yeast fermentation results in ethanol, but the answer is D somehow can someone explain?

                        Taaaa76
                        I was doing the same practise exam yesterday (neap 2022) ahaha.

                        So biomass is plant or animal material that can be sourced from various industries that have carbon rich compounds that glucose and other sugars can be extracted from. The biomass itself is the source of glucose and sugars as an input for fermentation. Then to produce bioethanol, Yeast is added to this biomass after it has been broken down to anaerobically ferment and produce ethanol as an output.
                        Therefore C would be incorrect because it cannot provide sugars and glucose for anaerobic fermentation. Although, I can see why you went with this answer.
                        D is the correct answer because wood pulp contains cellulose, which be broken down to produce glucose.
                        if this is still confusing or u have another question feel free to ask

                            Hi, i got this question in a practise exam:
                            Explain why RNA must be converted to DNA in RT-PCR
                            2 mark question.

                            Is RT-PCR on the study design??

                              Taaaa76 this was a question from the 2022 biology exam. It is on the study design I think.

                                  Hi, I have a question on meiosis, when describing how it can increase genetic diversity. Is recombination the same as like crossing over and independent assortment? What would be the difference if they aren't?

                                  A sample answer I found to this question I was doing said, "The genetic material is transferred between homologous chromosomes during recombination"

                                    ava recombination usually just refers to crossing over, since that's when some of genetic material is swapped between the homologous chromosomes to create genetically distinct homologous chromosomes. Independent assortment just refers to the lining up of the chromosomes on the metaphase plate, the maternal and paternal chromosomes randomly swapping their position either side of each other and creating unique combinations either side of this plate. Hope that makes sense. Maybe check with your teacher to confirm this.

                                    • ava replied to this.

                                        Does anyone know what biological implications mean? Such as when they ask for a biological implication about GMOs. I am struggling to find out what the term actually refers to. Thanks!
