Create a concept map to describe the processes of photosynthesis and cellular respiration occurring within a cell. Use the following bulleted list of words in your concept map. You may add more words. All the words must be connected to at least one other word in your map. Connect the words with lines and arrows and include linking words on your lines. You can link words more than once. By creating more than one link to a word you are creating cross-connections, which show a greater understanding of the concept. Refer to sample the concept map of cell membranes on page 30. energy electron transport system photosynthesis glucose cellular respiration light dependent reactions light energy carbon-fixation reactions chemical energy chlorophyll ATP chloroplasts ADP thylakoid membranes NAD+ photosystems NADP cxidation phosphorylation anaerobic respiration glycolysis aerobic respiration
The Correct Answer and Explanation is :
Here’s a concept map for the processes of photosynthesis and cellular respiration:
Photosynthesis:
- Light Energy → Chlorophyll → Light-Dependent Reactions
- Light-Dependent Reactions → ATP → Thylakoid Membranes
- Light-Dependent Reactions → NADP+ → NADPH
- Light-Dependent Reactions → Oxygen
- Light-Dependent Reactions → Electron Transport System
- Electron Transport System → ATP
- Carbon-Fixation Reactions → Glucose
- Glucose → Chemical Energy
- Chloroplasts → Photosystems → Light-Dependent Reactions
- Photosystems → NADP+ → NADPH
Cellular Respiration:
- Glucose → Glycolysis → Pyruvate
- Pyruvate → Aerobic Respiration → ATP
- Glycolysis → NAD+ → NADH
- NADH → Electron Transport System → ATP
- NAD+ → Oxidation
- Oxidation → Energy Release
- ATP → ADP → Phosphorylation
- Aerobic Respiration → Oxygen
- Anaerobic Respiration → Lactic Acid or Ethanol
- ATP → Energy
300-word Explanation:
This concept map connects the key terms related to photosynthesis and cellular respiration by showing how energy flows in a cell.
- Photosynthesis is the process by which plants convert light energy into chemical energy, which is stored in glucose. This process happens in the chloroplasts, particularly within the thylakoid membranes, where chlorophyll absorbs light energy. The light-dependent reactions use light to produce ATP and NADPH (through the electron transport system), and oxygen is released as a byproduct.
- In the carbon-fixation reactions, also known as the Calvin cycle, NADPH and ATP are used to convert carbon dioxide into glucose, a form of chemical energy. This glucose is vital for cellular processes and can later be used in cellular respiration to release stored energy.
- Cellular respiration is the process by which cells break down glucose to produce ATP, which is the main energy currency for the cell. Glycolysis breaks down glucose into pyruvate, which can proceed to aerobic respiration (using oxygen) or anaerobic respiration (without oxygen). In aerobic respiration, NADH produced in glycolysis passes electrons through the electron transport system to generate ATP.
- Phosphorylation occurs when ADP is converted into ATP through a process that releases energy. This process is crucial in both photosynthesis and cellular respiration, ensuring cells have a continuous supply of usable energy.
