What occurs during the process represented by the photosynthesis equation?
Photosynthesis is usually represented by the equation 6 CO2 + 6 H2O + light –> C6H12O6 + 6 O2. During this process, organisms such as plants go through the light-dependent and light-independent reactions to convert carbon dioxide and water into sugars and oxygen.
What is the importance of the process of photosynthesis?
It’s not oxygen production. The primary function of photosynthesis is to convert solar energy into chemical energy and then store that chemical energy for future use. For the most part, the planet’s living systems are powered by this process.
What is photosynthesis write the equation of photosynthesis?
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
What is an example of why the process of photosynthesis is important to life on Earth?
D) Green plants use photosynthesis to remove oxygen gas from the atmosphere and replenish the earth’s carbon dioxide. The process of photosynthesis is energy-releasing because the process converts light energy into free energy that can be used for cell functions.
What is the most important part of photosynthesis?
The most common and critical type of photosynthesis takes place in chlorophyll‐containing plants, algae, and cyanobacteria. These organisms capture radiant energy of the sun and, by utilizing carbon dioxide and water, convert it to chemical energy stored in molecules of carbohydrates.
What are the stages of photosynthesis and what are their products?
The stages of photosynthesis
|Light-dependent reactions||Thylakoid membrane||Light energy is captured by chloroplasts and stored as ATP|
|Calvin cycle||Stroma||ATP is used to create sugars that the plant will use to grow and live|
What are the two stages of photosynthesis and describe each stage?
The two stages of photosynthesis: Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle (light-independent reactions). Light-dependent reactions, which take place in the thylakoid membrane, use light energy to make ATP and NADPH.
What are the two stages where photosynthesis occurs?
Photosynthesis takes place in two stages: light-dependent reactions and the Calvin cycle.
What is the first stage of photosynthesis called?
Photosynthesis occurs in two stages. In the first stage, light-dependent reactions or light reactions capture the energy of light and use it to make the energy-storage molecules ATP and NADPH. During the second stage, the light-independent reactions use these products to capture and reduce carbon dioxide.
What are the two stages of photosynthesis quizlet?
What are the two stages of photosynthesis? 1=light reactions/light dependent reactions. 2=the calvin cycle/light independent reactions.

What occurs in the second phase of photosynthesis quizlet?
The second phase of photosynthesis is called the light independent reaction (or Calvin Cycle). absorb light energy and make ATP and NADPH.
How does NADP+ become Nadph?
In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. The lower energy form, NADP+, picks up a high energy electron and a proton and is converted to NADPH.
What is the main function of Nadph?
Function of NADPH NADPH function in transferring electrons and a hydrogen displaced by the energy of sunlight. The NADPH first accepts the electrons and hydrogen when special enzymes transfer these particles to the molecule NADP+
What is the role of NADP?
A major role of NADP is its role as co-enzyme in cellular electron transfer reactions. Moreover, the cell spends a significant amount of energy to keep NADP in its reduced form, thereby maintaining a readily available pool of electrons to reduce oxidized compounds. glutamate and proline) is also dependent on NADPH.
What is the difference between NADH and Nadph?
NADH is just a reduced form of NAD, meaning it has gained the [e¯] from the H atom it has bonded with. NADH is used in Catabolic reactions (like Respiration, breaking down Glucose) and NADPH is used in Anabolic reactions (like Photosynthesis, building glucose).
Where is NADH used?
NADH is used in the electron transport chain to provide energetic electrons.
What does the H stand for in NADH?
NADH stands for “nicotinamide adenine dinucleotide (NAD) + hydrogen (H).” This chemical occurs naturally in the body and plays a role in the chemical process that generates energy. People use NADH supplements as medicine.
What does NADH do in a cell?
The cofactor is, therefore, found in two forms in cells: NAD+ is an oxidizing agent – it accepts electrons from other molecules and becomes reduced. This reaction forms NADH, which can then be used as a reducing agent to donate electrons. These electron transfer reactions are the main function of NAD.
What is NADH and how is it produced?
In glycolysis and the Krebs cycle, NADH molecules are formed from NAD+. Meanwhile, in the electron transport chain, all of the NADH molecules are subsequently split into NAD+, producing H+ and a couple of electrons, too. In each of the enzymatic reactions, NAD+ accepts two electrons and a H+ from ethanol to form NADH.
What process does the cell go into when there is a low oxygen environment?
Cellular respiration can occur both aerobically (using oxygen), or anaerobically (without oxygen). During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts.
