Which of the following is the last step in the Oparin-Haldane Model for the beginning of life?   a. Membranes form around the first cells   b. Simple molecules assembled into building blocks   c. Polymers assembled from simple building blocks   d. Asteroids and meteors provide building blocks for life on earth
Animals obtain energy through a series of chemical reactions in which sugar (C6H12O6) and oxygen gas (O2) are reactants. This process produces water (H2O) and carbon dioxide (CO2 ) as waste products. How might you use a radioactive isotope to find out whether the oxygen in CO2 comes from sugar or from oxygen gas?
In 1941, biologists exposed photosynthesizing cells to water containing a heavy oxygen isotope, designated 180. The "labelled" isotope appears in the 02 gas released in photosynthesis, showing that the oxygen came from water. Where would the 180 have ended up if the researcher had used 180-labeled CO2 instead of H2O? A. ADP B. NADP+ C. Rubisco D. DP and NADP+ E. Glucose
