(Use the NAMES of the molecules) According to your equation, the process of cellular respiration uses and to produce and release . 3. In cellular respiration, chemical energy'ls released from_ molecules and transferred to molecules, which cels can use to provide energy for cellular processes 4. Was it difficult to rearrange your pieces to produce the equation for cellular respiration? Why or why not? Cellular respiration occurs in both plants and animals. Given what you know about animals, why does your position for COs and O 5. in the equation make sense? 6. Interpret the chemical reaction-what is the overall purpose of cellular respiration? What are the two main differences between the chemical reaction for photosynthesis and the chemical reaction for cellular respiration? 7. Extension Questions I. Cellular respiration occurs in BOTH plants and animals. Why do plants need cellular respiration? 2. Plants produce e carbon dioxide as a product of cellular respiration. But you know that plants release oxygen, not carbon dioxide. Develop a logical argument for how this is possible. HINT: Think about both chemical reactions and the speeds at which they could occur. usable energy through 3. Plants can make their own food through photosynthess and then break it down for u how your ßte might be different it you could make your own ess of cellular respiration. Analyze food through photosynthesis.Explanation / Answer
C6H12O6 (s) + 6O2 (g) ? 6CO2(g) + 6H2O (l) + heat
In cellular respiration, a glucose molecule is converted to energy by 6 molecules of oxygen. Leaving 6 moles of carbon dioxide and 6 moles of water. As cells derive energy through glucose which is the main substrate for energy production, oxygen molecules break the bonds in the glucose (bond breaking releases energy) and produce water and carbon dioxide. The energy produced through this process is used to convert ADP (Adenosine diphosphate) to ATP (Adenosine triphosphate) which are called the energy currencies of cell.
2. According to equation, the process of cellular respiration uses glucose and oxygen to produce water, carbon dioxide and release energy.
3. In cellular respiration, energy is released from glucose molecules and transferred to ADP molecules, which cells can use to provide energy for cellular process.
From the above explanation, glucose molecules are the main substrate through which cells derive energy and the energy which is produced is used to produce ATP from ADP.
5) In plants
6CO2 + 6H2O + light energy ? C6H12O6 + 6O2 (PHOTOSYNTHESIS)
In both plants and animals
C6H12O6 (s) + 6O2 (g) ? 6CO2(g) + 6H2O (l) + heat (CELLULAR RESPIRATION)
Given what I know about animals, the position for CO2 and O2 in the equation makes sense because oxygen which animals obtain are from plants (they breathe out oxygen) and the carbon-dioxide we breath out is the carbon source for the plants to produce glucose. So plants and animals exchange their released products to live.
6) Interpretation of chemical reaction, the overall purpose of cellular respiration
The overall purpose of cellular respiration is the hooking of phosphate molecule to ADP molecule to produce ATP (high-energy molecules).
Reason:
This is because ATPs can be stored by the cell and readily used if needed. Also the breaking of phosphate from ATP releases energy to drive the cells functions.
7) Two main differences between the chemical reaction for photosynthesis and chemical reaction for cellular respiration
From the equations shown in ANS 5,
1) Photosynthesis makes glucose, while cellular respiration breaks glucose to produce energy
2) Photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide
