Does respiration require chlorophyll?

Does respiration require chlorophyll?

Occurs in plants, protista (algae), and some bacteria. No catalyst is required for respiration reaction. Reaction takes places in presence of chlorophyll.

Is sunlight needed for respiration?

Respiration occurs in the mitochondria of plant cells, and it is a process that does not require light. While energy from the sun fuels parts of the process of photosynthesis, the energy needed for respiration comes from sugars, which are the products of photosynthesis.

Are light and chlorophyll required in photosynthesis or respiration?

Cellular Respiration in Plants Photosynthesis is the process used by plants and some bacteria to create energy from sunlight. Chlorophyll is the green pigment in plants that is responsible for this conversion process. In all other living things, they rely on the process of respiration to stay alive.

What is needed for respiration in plants?

Plants do require oxygen to respire, the process in return gives out carbon dioxide. Unlike humans and animals, plants do not possess any specialized structures for exchange of gases, however, they do possess stomata (found in leaves) and lenticels (found in stems) actively involved in the gaseous exchange.

What is chlorophyll in cellular respiration?

In eukaryotic cells these reactions occur in the organelle known as the chloroplast. In the chloroplast, chlorophyll is the pigment that absorbs the sunlight. Sunlight is converted to chemical energy in the form of ATP (adenosine triphosphate), which is the main energy-storing molecule in living organisms.

What is the main substrate for respiration?

Glucose
Glucose is the molecule normally used for respiration – it is the main respiratory substrate . Glucose is oxidised to release its energy, which is then stored in ATP molecules.

Why do plants need to respire?

Plants are no exception. They need to respire virtually all the time in order to supply their energy needs. They are not able to use the ATP generated in photosynthesis for these purposes. Plants respire in the normal way using glycolysis, Krebs cycle, oxidative phosphorylation etc.

Why is sunlight and chlorophyll not needed for respiration?

Sunlight and chlorophyll is not needed for (cellular) respiration, as its use is to burn food and other resources to make energy. A chlorophyll’s job is to utilize the energy from light to produce food and other resources, with oxygen and water as a byproduct.

What are the conditions needed for respiration in plants?

For respiration, sunlight and chlorophyll are needed.3. In old stems, gaseous exchange takes place through the stomata.4. Photosynthesis occurs only in chlorophyll – containing plants.5. Respiration which requires oxygen is known as anaerobic respiration.6.

How do photosynthesis and respiration take place in plants?

Photosynthesis and respiration take place all the time in plants.2. For respiration, sunlight and chlorophyll are needed.3. In old stems, gaseous exchange takes place through the stomata.4. Photosynthesis occurs only in chlorophyll – containing plants.5.

What is the difference between aerobic respiration and respiration?

Respiration which requires oxygen is known as anaerobic respiration.6. Aerobic respiration takes place in the absence of oxygen. State if the following statements are True or False. Correct the False statement. 1. Photosynthesis and respiration take place all the time in plants. 2. For respiration, sunlight and chlorophyll are needed.
