How is the production of NADPH useful for the process of photosynthesis?
Answers
The Calvin cycle is maintained and powered by the NADPH generated during the light-dependent stage of photosynthesis.
What is the role of NADPH is the photosynthesis?From the thylakoid to the stroma, NADPH moves. It is a high-energy electron carrier that transports both high-energy electrons and the hydrogen needed to make sugar.
NADPH will go to the Calvin cycle, where its electrons will be used to convert carbon dioxide into carbohydrates. ATP is the other component required by the Calvin cycle, and the light reactions also supply this.
NADPH is created during photosynthesis by using light energy in the chloroplasts' electron transport chain.
The Calvin cycle and subsequent processes that result in the production of carbohydrates can subsequently utilize it as a form of energy currency.
Therefore, the production of NADPH useful for the process of photosynthesis.

22.what products of photosynthesis and reactants for respiration belong in the box to complete the cycle?
A -hormones
B -chlorophyll a and chlorophyll b
C -ATP AND ADP
D -glucose and oxygen
Answers
Answer:
Glucose and Oxygen hope that helps.
Explanation:
The box in this question is likely referring to the carbon cycle, which is a cycle of biochemical reactions that involve the transfer of carbon between different forms in the environment. The products of photosynthesis and reactants for respiration that belong in the box to complete the cycle are glucose and oxygen.
What is photosynthesis ?Photosynthesis is the process by which plants use energy from the sun to convert carbon dioxide and water into glucose and oxygen. This glucose is then used by the plant for energy, and the oxygen is released into the atmosphere.
During respiration, the glucose is broken down in the presence of oxygen to release energy, which is then used by the plant for its various functions. The end products of respiration are carbon dioxide and water. Chlorophyll a and chlorophyll b are both types of pigments found in plants that are essential for photosynthesis.
They absorb energy from the sun and help convert carbon dioxide and water into glucose and oxygen. Hormones, on the other hand, are molecules that are produced by the plant to regulate its growth and development.
They are not directly involved in the carbon cycle. Finally, ATP and ADP are molecules that are involved in the transfer of energy within a cell. They are not directly involved in the carbon cycle, but they are essential for respiration as they help to break down glucose and release energy.
In summary, the products of photosynthesis and reactants for respiration that belong in the box to complete the cycle are glucose and oxygen.

D.

Answers
The salinity of the water is increased does the flow of weathered and dissolved rock material towards the ocean affect the chemical composition of the ocean. So, the correct option is C.
What is the Chemical composition of Ocean?Understanding the chemical properties of the ocean is essential because the marine environment supports the greatest abundance of life on Earth, whose life is largely composed of the same chemicals that make up seawater and salts.
The two important elements in sea water, after oxygen and hydrogen, are sodium and chloride where sodium and chloride combine to form the salt we know as table salt. The salinity of sea water is expressed as the ratio of salt (in grams) to liters of water.
Thus, the salinity of the water is increased does the flow of weathered and dissolved rock material towards the ocean affect the chemical composition of the ocean. So, the correct option is C.
