Photosynthesis is an endergonic
Is photosynthesis a reduction process?
The reduction of carbon dioxide into sugars and oxidation of water into molecular oxygen is involved in photosynthesis. … To produce carbon dioxide and water, the reverse reaction, respiration, oxidizes sugars.
How reduction reaction occur in photosynthesis?
Photosynthesis involves
the reduction of carbon dioxide into sugars and the oxidation of water into molecular oxygen
. The reverse reaction, respiration, oxidizes sugars to produce carbon dioxide and water.
What type of reaction is photosynthesis?
Photosynthesis is
an endothermic reaction
. This means it cannot occur without energy (from the Sun). The light required is absorbed by a green pigment called chlorophyll in the leaves.
Is photosynthesis an oxidation or reduction reaction?
Photosynthesis is
oxidation- reduction reaction
as the water ( loose electrons) is being oxidized and carbon dioxide( gains electrons) is being reduced…
What is photosynthesis formula?
The process of photosynthesis is commonly written as:
6CO
2
+ 6H
2
O → C
6
H
12
O
6
+ 6O
2
. 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 inside of a photosystem?
Each photosystem has two parts: a reaction center, where the photochemistry occurs, and
an antenna complex
, which surrounds the reaction center. The antenna complex contains hundreds of chlorophyll molecules which funnel the excitation energy to the center of the photosystem.
What are the two Assimilatory powers?
– The assimilatory power in photosynthesis is the power produced in the form of
ATP and NADPH2
. These molecules are formed during the evolution of oxygen and the photolysis of water.
Is photosynthesis exergonic or endergonic reaction?
Photosynthesis is
an endergonic
(energy-consuming) process. Cellular respiration is an exergonic (energy-releasing) process.
Which one is a Photophosphorylation?
Photophosphorylation is
the conversion of ADP to ATP using the energy of sunlight by activation of PSII
. This involves the splitting of the water molecule in oxygen and hydrogen protons (H
+
), a process known as photolysis.
What reactants in photosynthesis are reduced?
Water is oxidized in photosynthesis, which means it loses electrons, and
carbon dioxide
is reduced, meaning it gains electrons.
What is the connection of photosynthesis and oxidation reduction?
Photosynthesis involves oxidation and reduction
by oxidizing the oxygen in water and reducing the carbon in carbon dioxide
.
What are reduction reactions?
A reduction chemical reaction involves
increasing electrons associated with a single atom or a group of atoms
. A reduced atom therefore accepts electrons from another atom. The atom which supplies the electrons is thereby oxidized.
What are the 2 kinds of reaction in photosynthesis?
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 is given out during photosynthesis?
During photosynthesis, plants take in carbon dioxide and release
oxygen
. Plants take in carbon dioxide (CO
2
) and water (H
2
O) from the air and soil during photosynthesis. The plant then releases the oxygen into the atmosphere while storing energy in the glucose molecules.
What are reaction types?
Basic chemical reactions can be grouped into categories based on the types of changes that are occuring during the reaction. There are five basic categories –
synthesis, decomposition, combustion, single replacement, and double replacement
.
