Question

1)В чём состоит различие процессов дыхания и фотосинтеза? 2)Как живые организмы используют энергию,освобождаемую при дыхании?

Answer 1

1)Фотосинтез  -процесс образования органических веществ из неорганических в  зеленых частях растений , на свету . А дыхание  это  процесс расщепления веществ  из кислорода.
2)все, в том числе и человек.

Answer 2

1) Фотосинтез - процесс образования органических веществ из неорганических в зеленых частях растений, на свету. А дыхание это процесс расщепления веществ из кислорода.
2) На биосинтез веществ своего организма, на движение, на размножение.

Answer 3

Difference between Respiration and Photosynthesis

Respiration and photosynthesis are two fundamental processes that occur in living organisms. Here's a detailed explanation of the differences between these processes:

1) Respiration: Respiration is the process by which living organisms convert organic compounds, such as glucose, into energy in the form of ATP (adenosine triphosphate). It occurs in all living cells and is essential for the survival of organisms. Respiration can be divided into two types: aerobic respiration and anaerobic respiration.

- Aerobic Respiration: Aerobic respiration occurs in the presence of oxygen and is the most common form of respiration in living organisms. It involves the breakdown of glucose molecules to produce ATP, carbon dioxide (CO2), and water (H2O). The overall equation for aerobic respiration is:

Glucose + Oxygen → Carbon Dioxide + Water + Energy (ATP)

- Anaerobic Respiration: Anaerobic respiration occurs in the absence of oxygen. It is less efficient than aerobic respiration and produces less ATP. Anaerobic respiration can occur in different ways depending on the organism. For example, in humans, anaerobic respiration produces lactic acid, while in yeast, it produces ethanol and carbon dioxide.

2) Photosynthesis: Photosynthesis is the process by which green plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose and oxygen. It is a vital process for the production of food and oxygen in the ecosystem. Photosynthesis can be divided into two stages: the light-dependent reactions and the light-independent reactions (also known as the Calvin cycle).

- Light-Dependent Reactions: The light-dependent reactions occur in the thylakoid membranes of chloroplasts. They require sunlight and involve the absorption of light energy by chlorophyll and other pigments. This energy is used to split water molecules, releasing oxygen as a byproduct and generating ATP and NADPH.

- Light-Independent Reactions (Calvin Cycle): The light-independent reactions occur in the stroma of chloroplasts. They use the ATP and NADPH generated in the light-dependent reactions to convert carbon dioxide into glucose through a series of chemical reactions. This process is also known as carbon fixation.

In summary, respiration is the process by which organisms convert organic compounds into energy, while photosynthesis is the process by which green plants and some bacteria convert sunlight, carbon dioxide, and water into glucose and oxygen.
