What reaction produces O2?
When manganese(IV) oxide is added to hydrogen peroxide, bubbles of oxygen are given off. To make oxygen in the laboratory, hydrogen peroxide is poured into a conical flask containing some manganese(IV) oxide. The gas produced is collected in an upside-down gas jar filled with water.
What is the product of 2H2 O2 2H2O?
water
At what point in photosynthesis is oxygen released?
The chloroplast is involved in both stages of photosynthesis. The light reactions take place in the thylakoid. There, water (H2O) is oxidized, and oxygen (O2) is released. The electrons that freed from the water are transferred to ATP and NADPH.
What is another name for the light independent reactions?
Calvin-Benson cycle
What are the products of a light reaction?
The light reactions capture energy from sunlight, which they change to chemical energy that is stored in molecules of NADPH and ATP. The light reactions also release oxygen gas as a waste product.
What is one role of ATP in the light-independent reaction of photosynthesis quizlet?
What is one role of ATP in the light-independent reaction of photosynthesis? ATP supplies the energy to produce glucose and other carbohydrates. In the chemical equation for photosynthesis, carbon dioxide and water are converted to glucose and oxygen.
Which compound is a metabolic intermediate of the light-independent reactions in photosynthesis ATP?
3-PGA
What does ATP contribute to the reaction?
ATP provides the energy for both energy-consuming endergonic reactions and energy-releasing exergonic reactions, which require a small input of activation energy. When the chemical bonds within ATP are broken, energy is released and can be harnessed for cellular work.
What is used in light-independent reactions?
Oxygenic photosynthesis is composed of two stages: the light-dependent reactions and the light-independent reactions. The light-independent reactions use the ATP and NADPH from the light-dependent reactions to reduce carbon dioxide and convert the energy to the chemical bond energy in carbohydrates such as glucose.
Why is the light-independent reaction important to most ecosystems?
Although photosynthesis is most commonly associated with plants, microbial photosynthesis is also a significant supplier of chemical energy, fueling many diverse ecosystems. 1: The light-dependent reactions of photosynthesis (left) convert light energy into chemical energy, forming ATP and NADPH.
Is used ATP discarded by the cell as waste?
ATP provides energy for the mechanical functions of cells. Used ATP is discarded by the cell as waste.
Do light dependent reactions supply the Calvin cycle with CO2 and ATP?
The light-dependent reactions use energy from sunlight to produce ATP, NADPH, and oxygen. Light-dependent reactions take place within thylakoid membranes of chloroplasts (ATP and ADPH the cell can actually use in Calvin Cycle). The Calvin cycle uses ATP and NADPH to produce high-energy sugars.
Which process results in the greatest ATP output?
Answer Expert Verified. Explanation; -Electron transport is one of the steps of cellular respiration.
When ATP is broken down into ADP energy is?
When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP). Likewise, energy is also released when a phosphate is removed from ADP to form adenosine monophosphate (AMP).
What does ATP produce when broken down?
The by-products of the breakdown of ATP are adenosine diphosphate (ADP), which is the remaining adenosine and two (di) phosphate groups, and one single phosphate (Pi) that is ‘on its own’.
