What is water used for in photosynthesis?

While light energy can be easily absorbed from the sun and carbon dioxide from the atmosphere, water is sometimes scarce. Not only is water used directly in the process of photosynthesis for its hydrogen, it is also used to prevent dehydration, indirectly supporting the successful creation of food for the plant.

Why is water essential for light reactions?

Biology textbook solutions Photolysis of water (Splitting of H20) at Photosystem II in the chloroplast provides electrons to the chlorophyll to replace those displaced from the chlorophyll by light.

What is Water’s role in the light reaction of photosynthesis its electrons are used to form glucose its electrons are used to form Nadph its oxygen atoms are used to form Nadph its oxygen atoms are used to form ATP?

Photosynthesis uses carbon dioxide and water to assemble carbohydrate molecules and release oxygen as a waste product into the atmosphere. Photosystem I absorbs a second photon, which results in the formation of an NADPH molecule, another energy and reducing power carrier for the light-independent reactions.

Which process of photosynthesis is linked to the production of ATP quizlet?

H+ ions flow down their gradient and into the stroma, they pass through ATP synthase, driving ATP production in a process known as chemiosmosis.

Which of the following best describes photosynthesis?

Which of the following best describes photosynthesis? Photosynthesis converts radiant energy into chemical energy, Plants need sunlight, carbon dioxide, water, nutrients, and chlorophyll to complete photosynthesis, Photosynthesis produces carbohydrates.

Which is true of photosynthesis and cellular respiration?

Photosynthesis makes the glucose that is used in cellular respiration to make ATP. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration.

Where do photosynthesis and cellular respiration occur?

Photosynthesis occurs in the chloroplasts, whereas cellular respiration occurs in the mitochondria.

What role do plants play in the carbon cycle?

Green plants play a very important role in the carbon cycle. They absorb carbon dioxide (CO2) from the atmosphere and produce carbon-containing sugars. This process is called photosynthesis.

Why is cellular respiration essential for living?

All organisms respire to release energy to fuel their living processes. The respiration can be aerobic , which uses glucose and oxygen, or anaerobic which uses only glucose.
