Photosynthesis

This category is for questions about the chemical process in which autotrophic organisms use sunlight, carbon dioxide and water to make glucose, water and oxygen. This process is vital to life and is of great importance in biology.

How are photosynthesis and cellular respiration opposite in terms of oxygen?

The process of photosynthesis stores energy in the form of chemical bonds (in carbohydrates including glucose, or sugar) and in the process releases free oxygen by breaking down carbon dioxide. Cellular respiration absorbs free oxygen, to release energy stored in the chemical bonds of food. This oxidation creates carbon dioxide, completing the cycle of carbon through the biosystem.

(Some forms of respiration are anaerobic, not using oxygen, and break down carbohydrates in a different manner, releasing either carbon dioxide or methane. The net result is the same: removing energy from the carbohydrate bonds.)

If photosynthesis is the process that deposits energy in a savings account then what is cellular respiration?

Cellular respiration is the process by which cells break down glucose to produce energy in the form of ATP. It is like withdrawing money from that energy "savings account" created during photosynthesis to power the cell's activities.

Do plants respire during photosynthesis?

Yes, during photosynthesis plants take in carbon dioxide and release oxygen. However, they also undergo respiration, where they take in oxygen and release carbon dioxide. So, plants do respire during photosynthesis, but the overall process results in a net release of oxygen.

What is another name for a single celled blue green photosynthetic bacteria?

The prefix 'Cyano' is used to refer to any number of cyanobacteria that grow all over the planet. Cyan is used because of its use in latin to describe the exact color stated in the question: blue green.

What best describes the relationship between photosynthesis and respiration ATP molecules are produced in photosynthesis and used up in respiration Respiration is an?

Photosynthesis produces ATP molecules using light energy to convert CO2 and H2O into glucose and oxygen. Respiration breaks down glucose to produce ATP molecules, using oxygen and releasing CO2 and H2O as byproducts. This forms a cycle where ATP molecules are produced in photosynthesis and used up in respiration, illustrating their interdependent relationship in cellular energy production.

Which molecule from the Calvin cycle is used to replenish RuBP?

Glyceraldehyde-3-phosphate (G3P) is the molecule from the Calvin cycle that is used to replenish ribulose-1,5-bisphosphate (RuBP). G3P is produced during the reduction phase of the Calvin cycle and can be converted back to RuBP through a series of enzymatic reactions.

What inorganic ion is essential for chlorophyll production?

Magnesium is the essential inorganic ion required for chlorophyll production in plants. It is a component of the chlorophyll molecule and plays a key role in capturing light energy for photosynthesis.

What is the source of Energy for All Of The Processes that Occur on the Earth's surface?

The primary source of energy for all processes that occur on Earth's surface is the Sun. Solar energy drives weather patterns, plant photosynthesis, ocean currents, and the water cycle, among other vital processes that sustain life on our planet.

Does the process of photosynthesis occur during the winter?

Yes, photosynthesis can still occur during the winter, but at a slower rate due to decreased sunlight and colder temperatures. Evergreen plants, which retain their leaves throughout the year, can continue photosynthesizing during the winter. However, deciduous plants may shed their leaves and enter a dormant state until conditions become more favorable for photosynthesis.

Where does photosynthesis happen in a plant cell?

Photosynthesis happens in the chloroplasts of plant cells. This process uses sunlight to convert carbon dioxide and water into glucose and oxygen.

Can energy in glucose be released by cellular respiration?

Yes, energy in glucose is released by cellular respiration through a series of chemical reactions that break down glucose and convert it into ATP, the cell's main energy source. This process occurs in the mitochondria of cells.

Why does the rate of photosynthesis increase with increasing light intensity?

It increases when temperatures rise and in the winter when it gets cold it decreases and that is to protect the tree or plant. When the day is starting, it increses then peaks in the middle of the day, and then decreases at the end. Temperature determines how much light is givin to the plant.

What is the substance used to make energy for photosynthesis?

The substance used to make energy for photosynthesis is sunlight. Plants use light energy to convert carbon dioxide and water into glucose, a form of chemical energy that can be used by the plant for growth and development.

How is the equation for respiration related to the photosynthesis equation?

They both use the same things but photosynthesis's products are what respiration starts with like respirtion needs oxgyen and glucose or sugar and photosynthesis is what give the oxgyen and glucose (sugar).

Organelles in plant cells that function in photosynthesis or storage are called?

Organelles in plant cells that function in photosynthesis or storage are called chloroplasts. Chloroplasts allow plants to capture the energy of the sun. Vacuoles are involved in storage of soluble carbohydrates or proteins.

What is the word and symbol for photosynthesis?

The word Equation is Carbon dioxide+water---->glucose+oxygen and the symboly eqation is 6CO2 + 6H2O ---> C6H12O6 + 6O2

What does photosynthesis create?

Photosynthesis produces glucose (C6H12O6) which is required by organisms for respiration, it also gives off bi-products of O2 and water, the oxygen is released into the atmosphere or recycled by the plant in its own respiration reactions.

What are the parts of photosynthesis?

Photosynthesis consists of two main parts: the light-dependent reactions, which occur in the thylakoid membranes of chloroplasts and require sunlight to produce ATP and NADPH, and the light-independent reactions (Calvin cycle), which take place in the stroma of chloroplasts and use ATP and NADPH to convert carbon dioxide into glucose.

What are the waste products in photosynthesis?

The waste product of photosynthesis is oxygen, which is released into the atmosphere as a byproduct of the light-dependent reactions. This oxygen is crucial for many organisms, including humans, as it is essential for respiration.

What is reversible formula for photosynthesis and respiration?

Photosynthesis Needs light energy, co2, and h2o. It gives off Glucose and o2. Respiration needs o2 and glucose. It gives of energy, o2, and h2o.

What are the clusters of photosystems?

The two clusters of photosystems in plants are Photosystem I (PSI) and Photosystem II (PSII). PSII functions first in the photosynthetic electron transport chain, followed by PSI, and they work together to absorb light energy and carry out the reactions of photosynthesis.

What is produced by the light reaction of photosynthesis?

The light reaction of photosynthesis produces ATP (adenosine triphosphate), NADPH, and oxygen. ATP and NADPH provide the energy and reducing power needed for the Calvin cycle (dark reactions) to produce sugar molecules.

Where is the site of the photosystems in the light-dependent reactions of photosynthesis?

The photosystems in the light-dependent reactions of photosynthesis are located in the thylakoid membranes of the chloroplast. Photosystem I and Photosystem II are embedded in the thylakoid membrane and are responsible for capturing and converting light energy into chemical energy.
