Answer:
<u>Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.</u>
Explanation:

Answer: In photosynthesis, the Electron Transport Chain consists of 2 photo systems which use light energy from the sun. The ATP synthase uses the proton gradient established from the ETC to create more energy. ATP is produced from ATP synthase. NADPH is produced from the NADP reductase process.
Answer:Carbon has four valence electrons, so it can achieve a full outer energy level by forming four covalent bonds. When it bonds only with hydrogen, it forms compounds called hydrocarbons. Carbon can form single, double, or triple covalent bonds with other carbon atoms.
