Review your understanding of photosynthesis in organisms with this free article aligned to NGSS standards.
•Many organisms make their own food through photosynthesis. Plants, algae, and some unicellular organisms do photosynthesis.
•Photosynthesis is powered by energy from sunlight. This energy is used to rearrange atoms in carbon dioxide and water to make oxygen and sugars.
•Carbon dioxide and water are inputs of photosynthesis. These inputs come from the environment.
•Oxygen and sugars are outputs of photosynthesis.
•The oxygen is released into the environment.
•The sugars can provide chemical energy. This energy can be used by the organism to live and grow. The sugars can also be used to build the organism’s structures, or they can be stored for later use.
Jul 17, 2016 · Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.
- Excellent question. The major reasons that I know of: 1) The high energy bonds in ATP are (by definition) unstable, so for long term storage of ene...
- When you add water, you can separate a compound into two. For example in hydrolysis of an ester, when you add water you get alcohol and carboxylic...
- The reason for this is simply because Photosystem I was discovered first, and Photosystem II was discovered second. You're right, it is confusing b...
- Both reactions, the light-depended reaction and the Calvin's cycle OCCURS ONLY in the light (and out of color spectrum, mainly blue and red colors...
- Glucose is utilised in respiration and excess glucose is stored in the form of starch.... The o2 released might be utilised by humans etc
- Pi stands for inorganic Phosphate... It is described in chemistry as the phosphoryl group, i.e. PO3 with a 2- charge.... This phosphate bonds with...
- It is likely that your colored water is not purely filtering those individual wavelengths. As such, the green water is still allowing some blue and...
- Photosynthesis is extremely important! It is the process in plants that allows it to harness energy from sunlight and convert it into chemical ener...
- ATP is Adenosine TriPhosphate, with three phosphates, and lots of energy stored in bonds. ADP is Adenosine DiPhosphate, with two phosphates, and so...
Here is a general diagram of the cycle: See a diagram that shows the molecular structures.

Apr 21, 2020 · Photosynthesis occurs in two stages: 1) The Light-dependent Reaction. Takes place in the thylakoid membranes of chloroplasts only during the day in the presence of sunlight. High-energy phosphate molecules adenosine triphosphate ( ATP) and the reducing agent NADPH are produced with the help of electron transport chain.

In photosynthesis, the plant cells use the ATP and NADPH formed during photophosphorylation to reduce CO 2 to sugar, (as we will see, specifically G3P, an intermediate in glycolysis also) in what are called the dark reactions.
