Write the overall equation for cellular respiration. (1 point) 45. Explain the connection between cellular respiration and photosynthesis. (2 points) The products of photosynthesis are used as reactants for cellular respiration and the products of cellular respiration are used as reactants for photosynthesis. The two processes are interdependent on each other. 46. Explain the steps of glycolysis in words. (4 points) 1. Glucose is converted into a new 6-C compound by using 2 ATP’s 2. The 6-C compound is then split into two 3 carbon molecules of G3P 3. The 2 G3P molecules are then oxidized into 2 new 3-C molecules by reducing 2 NAD+ into 2 NADH & 2H+ 4. Finally, 4 ADP molecules are added to the 3-C molecules, forming 2 molecules of pyruvic acid, 4 ATP’s, & 2 H2O Cellular Respiration Study Guide Biology 47. Illustrate the process of glycolysis.
