Cellular Respiration and Photosynthesis Worksheet All organisms need energy to live. Plants get their energy from the sun to make ATP and sugar. Animals have to eat plants (or other organisms) to get sugar to make ATP. This worksheet focuses on comparing and contrasting the two processes of photosynthesis (making sugar) and cellular respiration (breaking down sugar). 1. Below is a picture of a cell. Label the locations of the three major pathways involved in cellular respiration. 2. Electron carriers play a major role in cellular respiration. What are the electron carriers and where during the process of cellular respiration do they get their electrons (become reduced)? 3. Electron carriers are also important in photosynthesis. What is the electron carrier involved in photosynthesis and when during the process of photosynthesis does it get its electron (become reduced)? 4. Plants consume CO2 and produce O2 during photosynthesis. Cellular respiration consumes O2 and produces CO2. When does both the consumption and production of O2 and CO2 occur in the pathways? a. CO2 is consumed during ___________________________________________ b. O2 is consumed during ____________________________________________ c. CO2 is produced during ____________________________________________ d. O2 is produced during _____________________________________________ CYTOSOL MITOCHONDRION 5. Below is a chloroplast. Label where the light and dark reactions take place. 6. Electron transport chains (for setting up a proton gradient) and ATP synthase are important for making ATP during both photosynthesis and cellular respiration. Label the following in the diagram below: For mitochondrion: intermembrane space, inner membrane, matrix For chloroplast: thylakoid space, thylakoid membrane, stroma Label where the concentration of protons is high and where is it low ATP Electron transport chain ATP synthase ADP + i P Mitochondria+ Chloroplast+
