What is the CHEMICAL EQUATION for PHOTOSYNTHESIS?

17 answers

The chemical equation for photosynthesis is:

6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2

This equation represents the process of photosynthesis, where carbon dioxide (CO2) and water (H2O) react in the presence of light energy to produce glucose (C6H12O6) and oxygen (O2).
Name/list the REACTANTS in PHOTOSYNTHESIS.
The reactants in photosynthesis are:

1. Carbon dioxide (CO2): This is a gas that is present in the atmosphere and is taken in by plants during photosynthesis.
2. Water (H2O): This is obtained by plants through their roots and is transported to the leaves. Water is split during photosynthesis to provide electrons and protons for the formation of glucose.
3. Light energy: This is absorbed by a pigment called chlorophyll, which is found in the chloroplasts of plant cells. Light energy is necessary to drive the chemical reactions of photosynthesis.
Name/list the PRODUCTS of PHOTOSYNTHESIS.
The products of photosynthesis are:

1. Glucose (C6H12O6): This is a simple sugar that is synthesized during photosynthesis and serves as the main source of energy for plants. Glucose is also used to produce other carbohydrates, such as starch and cellulose.
2. Oxygen (O2): This is a byproduct of the photosynthesis process. Plants release oxygen into the atmosphere as a waste product, which is essential for the survival of many organisms that rely on oxygen for respiration.
What is the CHEMICAL EQUATION for CELLULAR RESPIRATION?
The chemical equation for cellular respiration is:

C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + energy

This equation represents the process of cellular respiration, where glucose (C6H12O6) and oxygen (O2) react to produce carbon dioxide (CO2), water (H2O), and energy. Cellular respiration is the process by which living organisms convert glucose into usable energy in the form of ATP (adenosine triphosphate).
Name/list the REACTANTS in CELLULAR RESPIRATION.
The reactants in cellular respiration are:

1. Glucose (C6H12O6): This is a sugar molecule that serves as the main source of energy for cellular respiration. Glucose is obtained from the breakdown of carbohydrates in our diet or synthesized through other metabolic processes.
2. Oxygen (O2): This is a gas that is obtained through respiration and is necessary for the process of cellular respiration. Oxygen serves as the final electron acceptor in the electron transport chain, which is an important part of aerobic respiration.
Name/list the PRODUCTS of CELLULAR RESPIRATION.
The products of cellular respiration are:

1. Carbon dioxide (CO2): This is a gas that is produced as a waste product during cellular respiration. Carbon dioxide is released into the surrounding environment.
2. Water (H2O): This is also produced as a waste product during cellular respiration. Water is a byproduct of the electron transport chain and is formed when oxygen accepts electrons and combines with hydrogen ions (protons).
3. ATP (adenosine triphosphate): This is the primary energy currency of cells. ATP is produced during cellular respiration and is used to power various cellular processes and activities.
In which cellular organelle does photosynthesis take place?

Chloroplast

Mitochondria
The correct answer is chloroplast. Photosynthesis takes place in the chloroplasts of plant cells. Chloroplasts are organelles that contain the pigment chlorophyll, which is responsible for capturing light energy and initiating the process of photosynthesis.
In what cellular organelle does cellular respiration take place?

Chloroplast

Mitochondria
The correct answer is mitochondria. Cellular respiration takes place in the mitochondria of cells, specifically in the inner membrane called the cristae. Mitochondria are responsible for producing the majority of ATP through aerobic respiration, which involves the breakdown of glucose and the use of oxygen.
How are PHOTOSYNTHESIS and CELLULAR RESPIRATION related?
Photosynthesis and cellular respiration are closely related as they are interconnected processes that occur in living organisms. They have a reciprocal relationship.

Photosynthesis, which occurs in plants, algae, and some bacteria, is the process by which light energy is converted into chemical energy in the form of glucose and oxygen is released as a byproduct. The equation for photosynthesis is:

6 CO2 + 6 H2O + light energy → C6H12O6 + 6 O2

Cellular respiration, on the other hand, occurs in all living organisms, including plants, animals, and microorganisms. It is the process by which cells break down glucose and other organic molecules to release energy in the form of ATP. The equation for cellular respiration is:

C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + energy (ATP)

The connection between these two processes is that the products of photosynthesis (glucose and oxygen) serve as the reactants for cellular respiration. Glucose produced by photosynthesis is broken down during cellular respiration to release energy for cellular activities, and oxygen produced during photosynthesis is used as the final electron acceptor in the electron transport chain of cellular respiration.

In summary, photosynthesis captures light energy to convert it into chemical energy (glucose) and release oxygen, while cellular respiration breaks down glucose and consumes oxygen to release energy in the form of ATP and produce carbon dioxide and water. These two processes are crucial for the exchange of gases (oxygen and carbon dioxide) and energy in living organisms.
