What two processes have to occur for photosynthesis to take place?

Photosynthesis requires two processes to occur: light reactions and dark reactions. During light reactions, light energy is absorbed by chlorophyll in the chloroplasts, which converts it into chemical energy in the form of ATP and NADPH. These energy-carrying molecules are then used in the dark reactions, where carbon dioxide is fixed and converted into glucose through the Calvin cycle.


What is the relationship between the light and dark reactions in photosynthesis and how do they work together to convert light energy into chemical energy?

The light reactions and dark reactions in photosynthesis are two stages that work together to convert light energy into chemical energy. In the light reactions, light energy is absorbed by chlorophyll in the chloroplasts, leading to the production of ATP and NADPH. These molecules are then used in the dark reactions, also known as the Calvin cycle, to convert carbon dioxide into glucose. Overall, the light reactions provide the energy needed for the dark reactions to occur and for the conversion of light energy into chemical energy.


What happens during each each of the two stages of photosynthesis?

These stages are called the light reactions and the dark reactions. The light reactions take place in the presence of of light. The dark reactions do not require direct light, however dark reactions in most plants occur during the day.


Which types of reactions are characterized by two reactants?

Bimolecular reactions involve two reactant molecules coming together to form a new product. This can include reactions such as addition, substitution, and some types of elimination reactions.


What are two chemical reactions that are necessary to give cell energy?

This energy is derived from the chemical bond energy in food molecules, which thereby serve as fuel for cells. The first step is the enzymatic breakdown of food molecules in digestion, and the second step that converts glucose molecules is called glycolysis.


How are the light and dark reactions linked together?

The light reactions of photosynthesis produce ATP and NADPH, which are then used in the dark reactions (Calvin cycle) to convert carbon dioxide into sugars. The ATP and NADPH generated in the light reactions provide the energy and reducing power needed for the dark reactions to occur. In this way, the two sets of reactions are interdependent and work together to sustain the overall process of photosynthesis.


What product of light reactions are required for the dark reactions?

The inputs of the Dark Reaction are NADPH, ATP, and CO2. The NADPH and ATP, which were produced in the Light Reactions, fix the carbon into a carbohydrate such as glucose. Enzymes are also needed for the Dark Reaction to take place. One such enzyme is Rubisco, which interacts with CO2 and RuBP in the first step of the Dark Reaction.


Which set of chemical reactions is performed by the chloroplast of the cell?

There are two reactions. Those are dark reaction and light indipendant reaction.


What are two other names for the light independent?

Calvin Cycle or Dark Reactions


All of the chemical reactions of the cell are called?

The chemical reactions of the cell are called metabolism. Metabolism consists of two main types of reactions: catabolic reactions, which break down molecules to release energy, and anabolic reactions, which build molecules using energy. These reactions are essential for the cell to function and maintain life.


When glucose is split during glycolysis two molecules of?

When glucose is split during glycolysis, two molecules of pyruvate are produced. This process occurs in the cytoplasm of the cell and involves a series of enzymatic reactions that convert one molecule of glucose (a six-carbon compound) into two three-carbon molecules of pyruvate. Additionally, glycolysis generates a net gain of two ATP molecules and two NADH molecules, which are important for cellular energy and redox reactions.


Series of reactions that produce two ATP molecules by breaking down a glucose molecule to pyruvic acid?

Glycolysis is a series of reactions in which a glucose molecule is broken down into two molecules of pyruvic acid, producing two molecules of ATP. This process occurs in the cytoplasm of the cell and is the first stage of cellular respiration.
