Question

1. What is the Photosynthesis EQUATION? What is being consumed and what is produced?

Answer 1

1. 6CO2 + H2O -----> C6H12O6 + 02

2. The idea of photosynthesis or light dependent reactions is to convert solar/light energy into chemical energy by the form of ATP and NADPH. CO2 and Water are consumed and react to release Glucose and 02. Approximately 36-38 ATP produced.

3. Water is the source of hydrogen atoms in the glucose (sugar) created by the photosynthesis reaction.

4 .
Step 1) The light absorbed by chlorophyll causes a transfer of electrons and H+ from H20 molecules already present. This causes the H20 to split into molecular 0xygen (02) and a H+ ion.

Step 2.) The O2 is released (we breathe it) and the H+ bonds to NADP+ creating NADPH

Step 3) ATP is formed through photophosphorylation. (ADP gets a phosphate group added to it creating ATP)

Step 4.) The NADPH and the ATP created here go on to fuel the reactions in the second part of photosynthesis - The Calvin Cycle

5. The Calvin cycle is a metabolic process that uses the carbon from carbon dioxide, along with energy in the form of ATP, to produce sugar.
A G3P molecule contains three fixed carbon atoms, so it takes two G3Ps to build a six-carbon glucose molecule. It would take six turns of the cycle.

6. To help synthesize carbohydrates for energy

7. In fixation, the first stage of the Calvin cycle, light-independent reactions are initiated; CO2 is fixed from an inorganic to an organic molecule. In the second stage, ATP and NADPH are used to reduce 3-PGA into G3P; then ATP and NADPH are converted to ADP and NADP +, respectively
