Question

41) Glucose is a 6-carbon molecule. When respiration is complete, where can you find these carbons?  
        A. In DNA double helix as part of genes        B. Used in transcription to make proteins
        C. Breathed out during respiration as CO2        D. Used to make lipids in bilayer

42) Plants take in CO2 through their stomata. What do they do with the molecule?
        A. Incorporate it into their DNA.        B. Use it to make glucose.
        C. Make chlorophyll pigment.        D. Control pH of their cells.

43) The scientific idea which proposes that the first eukaryotic cell resulted from a large anaerobic bacterium engulfing a small aerobic one is called ________theory.
        A. natural selection    B. macrophage         C. endosymbiotic     D. diploid

44) When the sun hits chlorophyll, ________________ is knocked out of the chlorophyll molecule and eventually ends up in ___________.
        A. protons; CO2        B. electrons; glucose    C. pigments; soil        D. electrons; Rubisco

Answer 1

41. C,

6 MOLECULE OF GLUCOSE IN THE PRESENCE OF OXYGEN, GIVES 6 MOLECULES OF CARBON DIOXIDE AND 12 MOLECULES OF WATER.

42. B

Plants uses stomata to absorb carbon dioxide from the atmosphere and hence convert it into glucose.

43. C

This theory states that one prokaryote engulfed another prokaryote to form a eukaryote. The prokaryote which was engulfed further behaved like the organelle inside the cell.

44. B

The chlorophyll helps in photosynthesis this resulting in the formation of glucose.
