The carbon source for organisms that make their food from photosynthesis is?
the carbon source from photosynthesis is CO2 in the atmsphere. Carbon is the second most abundant element in living matter.
What are the 3 things that are needed for photosynthesis?
Typical photosynthesis, ie, the formation of carbohydrates, requires carbon dioxide (from the air), hydrogen (usually from water) and sunshine. Of course a plant with chlorophyll-containing parts is also needed since this is where it all takes place.
Is ATP a net product or reactant of photosynthesis?
In the chloroplast, the thylakoid membranes are the sites of the light reactions, whereas the Calvin cycle occurs in the stoma. The light reactions use solar energy to create ATP and NADPH, which supply chemical energy and reducing power, respectively, to the Calvin cycle. The Calvin cycle incorporates CO2 into organic molecules, which are converted to sugar.
Second step in photosynthesis?
The second step in the Photosynthesis is the Calvin Cycle. It is also known as the Light-Independant Reactions or the Dark Reactions. :3
Where is the second stage of photosynethsis?
The second part of photosynthesis is called the light independent. it does not require light for it can also be refair to as the dark phase. The first part of photosynthesis is called the light dependent for its requires light.

the carbon source from photosynthesis is CO2 in the atmsphere. Carbon is the second most abundant element in living matter.
What are the dark reactions?
It is photosynthesis where light is not needed. It is a nickname for the Calvin-Benson cycle which is the second main step of photosynthesis. It utilizes the ATP and NADPH produced from the light-reactions as well as carbon dioxide from the air in order to produce glucose.
During which stage of photosynthesis does carbon fixation take place?
During the Light Independent Stage or second stage of photosynthesis.
When does photosynthesis happen night or day?
Most types of photosynthesis (C3 & C4) occur only during the day, however plants that use CAM photosynthesis open their stomata during the night to take in the gases essential for photosynthesis withoug losing the water in the cells. They then use the CO2 to produce glucose throughout the day.

What are the 2 main reactions in photosynthesis?
Photosynthesis happens in two stages, also called reactions. The first stage is the light-dependent stage. In this stage light energy is absorbed by chlorophyll and converted into chemical energy, and water is split to produce hydrogen. The unwanted oxygen from the water is released. The second stage is the light-independent stage. In this stage the chemical energy and the hydrogen from the first stage are used to convert carbon dioxide into carbohydrates, such as glucose. More details can be found on this site by searching for photosynthesis.
Which processes add and remove carbon dioxide from the atmosphere?
The calvin cycle removes carbon dioxide from the air and uses it to form carbohydrates in plants. The burning of fossil fuels releases trapped carbon dioxide from the fuel and releases it back into the atmosphere.
Is ATP a net product or reactant of photosynthesis?
In the chloroplast, the thylakoid membranes are the sites of the light reactions, whereas the Calvin cycle occurs in the stoma. The light reactions use solar energy to create ATP and NADPH, which supply chemical energy and reducing power, respectively, to the Calvin cycle. The Calvin cycle incorporates CO2 into organic molecules, which are converted to sugar.
Why is water needed in photosynthesis?
It is a part of the process of how a plant produces glucose and other sugars in order to live. In order to photosynthesize, a plant needs water from what is in the air (measured by humidity) or from what it takes from the ground in its roots, or on its leaves when it rains, and carbon dioxide from the atmosphere. The plant uses these two elements to produce by products oxygen, which is released as a waste product to the atmosphere, and glucose, which is uses for energy. Specifically, water is needed for photosynthesis because it's electrons are used to replenish the lost electrons from the chlorophyll in photosystem II. The hydrogens from water are also used to make a proton gradient that powers the ATP synthase which is used to make ATP for the Calvin cycle. The oxygen is a waste product of the process.
What step of photosynthesis is glucose produced?
Sugar is produced in the last stage of photosynthesis, the Calvin cycle.
Photosynthesis occurs in what structure?
Photosynthesis occurs in the chloroplast (organelle present in the plant cells) the first part of photosynthesis (light dependent reaction) occurs in on the thylakoid membranes and the second part (Calvin cycle) occurs in stroma of the chloroplast.
Second step in photosynthesis?
The second step in the Photosynthesis is the Calvin Cycle. It is also known as the Light-Independant Reactions or the Dark Reactions. :3
