Unit 5 Cell energy systems

Both photosynthesis and cellular respiration take place in the leaves of plants. The diagram below shows a plant undergoing photosynthesis. WHAT PRODUCTS FROM PHOTOSYNTHESIS ARE USED IN CELLULAR RESPIRATION?

• water and glucose
• glucose and oxygen
• water and carbon dioxide
• glucose and carbon dioxide

In the contained ecosystem below, the organisms will need to get food and any other requirements within the system. How do the plants get enough carbon dioxide to go through photosynthesis?

• carbon dioxide is stored in the glass container
• water plants do not need carbon dioxide to undergo photosynthesis
• water will slowing dissolve the sand and dirt, releasing carbon dioxide
• living things within the system will produce carbondioxide as products of cellular respiration

How are cellular respiration and photosynthesis related, in terms of energy?

• energy captured in photosynthesis is used to power cellular respiration
• energy transformed in cellular respiration is used to power photosynthesis
• photosynthesis and cellular respiration perform the same task in terms of energy transformation
• energy is not involved in either photosynthesis or cellular respiration

During photosynthesis, plant cells take in water (H2O) and carbon dioxide (CO2) and release oxygen (O2). How is this different from what takes place during aerobic respiration?

• during aerobic respiration, cells release O2 and take in CO2, H2O, and ATP
• during aerobic respiration, 
  O2 is inhaled and CO2 and H2O are exhaled
• during aerobic respiration, cells use ATP to cinvert insulin to glucose and CO2
• during aerobic respiration, the mitochondria form CO2 during the process of fermentation

During cellular respiration the cells within a white-tailed rabbit break down glucose that is absorbed through digestion of plant materials. What product of this process is then released into the atmosphere as waste and used by other plants to create more glucose?

• oxygen
• methane
• carbon dioxide
• carbon monoxide

Which type of molecule is used by cells throughout the body as the primary energy source?

• proteins
• nucleic acids
• carbohydrates
• lipids

Which type of organic molecule is made up of fatty acids and glycerol?

• lipids
• proteins
• carbohydrates
• nucleic acids

During cellular respiration in eukaryotic cells, glucose is broken down into carbon dioxide and water molecules. What energy source is produced during this process of breaking down the glucose molecules?
