Define the process of photosynthesis

Answer 1

• Photosynthesis and cellular respiration are similar because they are opposite processes, the equations are reverse, both take place in plants, some bacteria/prokaryotes, and algae. They are different because cellular respiration releases energy, takes place in mitochondria, releases carbon dioxide and water, and uses oxygen to release energy from food. Photosynthesis stores energy, takes place in chloroplasts, produces carbon dioxide and water, and releases oxygen into the atmosphere and food (sugar).
• Photosynthesis combines CO2 and H2O, producing glucose and O2
• • Captures about 1% of energy= in variety of organism
  • Anoxygenic without oxygen in purple bacteria, green sulfur bacteria, green nonsulfur bacteria, and heliobacteria
  • Oxygenic in cyanobacteria, 7 algae groups all land plants= in leaves with chloroplasts
  • Three stages
  • • Capture energy fron sun
    • Use energy to make ATP and reduce NAP+ to NADPH
    • Use ATP and NADPH to power synthesis of organic molecules from CO2 in air
  • First two- light-dependent --> third carbon fixation- with cylic series of reactions as long as have stuff
  • • Light-independent- third in light or not as long as have ATP or NADPH
  • Carbon dioxide + water + light --> glucose + water + oxygen = reverse of respiration
  • Oxidation of H2O and reduction of CO2 requires light

Answer 2

1)Energy transfer in antenna chlorophyll.

2)Transfer of electrons in photochemical reactions.

3)Electron transport chain and ATP synthesis.

4)Carbon fixation and export of stable product.

Answer 3

Photosynthesis:

The process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct

Hope I helped :)

Answer 4

Photosynthesis is the process by which plants, algae, and some bacteria convert light energy from the sun into chemical energy in the form of glucose. This process involves the absorption of light by chlorophyll in chloroplasts, which then converts carbon dioxide and water into glucose and oxygen. The glucose serves as a source of energy for the organism, while the oxygen is released into the atmosphere as a byproduct.

Answer 5

photosynthesis is the building up of complex molecules from simpler substances requires energy & enzymes. The enzymes are in the plant cells, and the energy comes from sunlight.
