Which process involves ribulose bisphosphate?

Ribulose bisphosphate is involved in the Calvin cycle, a process that occurs in the chloroplasts of plants where carbon dioxide is fixed to produce sugars. This molecule plays a key role in capturing and incorporating carbon into organic compounds during photosynthesis.

What side of the photosynthesis formulas is the reactant?

The reactants in any chemical or biochemical equation are normally placed to the left of the "yields" sign (the arrow pointing to the right), while the products of the reaction are normally placed to the right.

How might different rates of photosynthesis in different light intensities affect ecosystems?

say there was a pondweed in a beaker with tonnes of light and a sea slug was put in with it they will both survive due to photosynthesis. if a pondweed was in a beaker and had no light with a sea slug the sea slug will die because the plant can't photosynthesis and will respire

What is the main product of photosynthesis that is stored in plants?

Glucose (C6H12O6) and oxygen gas (O2) are the products of photosynthesis. The glucose is the main product of the Calvin cycle (a.k.a. the Dark Reactions) and the oxygen gas comes from the H2O being split so its electrons can go to replace the chlorophyll's lost electrons. The Hydrogen ions make the proton gradient while the Oxygen gas is a by-product. This O2 ends up being released for cellular respiration.

What is the main transportation system of a plant?

The main transportation system of a plant is its vascular system, which includes xylem and phloem. Xylem transports water and minerals from the roots to the rest of the plant, while phloem transports sugars produced during photosynthesis to various parts of the plant for energy or storage.

What two products are created by photosynthesis?

The two main products of photosynthesis are glucose (sugar) and oxygen. Through the process of photosynthesis, plants convert carbon dioxide and water into glucose as a source of energy and oxygen as a byproduct released into the atmosphere.

What is chemosynthesis and how is it different from photosynthesis?

Chemosynthesis is the process by which organisms use chemical energy to produce food. This is different from photosynthesis, which is the process by which green plants and some other organisms use sunlight to convert carbon dioxide and water into glucose for energy. Chemosynthesis does not require sunlight and can occur in environments where light is not available, such as deep-sea hydrothermal vents.

What happened when you placed Elodea at the light compensation point?

When Elodea is at the light compensation point, the rate of photosynthesis matches the rate of respiration. This means that the amount of oxygen being produced through photosynthesis is equal to the amount being consumed through respiration, resulting in no net change in oxygen levels in the water.

Why does the pH of the cell become more basic during photosynthesis?

During the light reactions of photosynthesis, protons (H+) are ferried into the thylakoid space using the energy from the excited electrons in Photosystems 680 and 700. H+ causes buildup of hydronium (H3O+) ions in water, which are acidic.

Which part of leaf is responsible for photosynthesis?

Chloroplasts are the part of the leaf responsible for photosynthesis. These organelles contain chlorophyll, the pigment that captures light energy and facilitates the conversion of carbon dioxide and water into glucose and oxygen during photosynthesis.

Do leaves permit entry of carbon dioxide and roots permit entry of water?

No, leaves primarily allow for the entry of carbon dioxide through tiny openings called stomata while roots primarily absorb water and minerals from the soil. Leaves play a role in gas exchange for photosynthesis, while roots are responsible for water and nutrient uptake.

What is photosynthesis important in the carbon cycle?

Photosynthesis is important in the carbon cycle because it is the process by which plants, algae, and some bacteria convert carbon dioxide from the atmosphere into organic compounds like glucose. This removes carbon dioxide from the atmosphere, helping to regulate the Earth's climate and providing the foundation of the food chain for all living organisms.

Do leaves of plants carry out photosynthesis?

Carotenoids are a group of accessory pigments which occur in all photosynthetic organisms. They contain about forty carbon atoms, often without oxygen atoms and are fat soluble. They are chemically unrelated to chlorophyll and consist of rings connected by long chains of carbon atoms. They absorb light maximally at wavelengths between 460 and 550 nm and are therefore yellow, red or orange in colour as they reflect the wavelengths in this part of the spectrum. Carotenoids are found in all photosynthetic organisms.

Can photosynthesis happen without enzymes?

Yes. Photosynthesis is an anabolic reaction, meaning energy is required to make the reaction run. Enzymes are especially important in these reactions because they lower the activation energy (Ea) of the reaction. This allows compounds to be combined and transformed with less energy.

How do you perform cuntilingus?

Perform cunnilingus by starting with gentle kissing and licking around the vulva and clitoris. Use your tongue to explore different areas, varying pressure and speed based on your partner's response. Communicate with them to understand what feels good and continue to be attentive to their reactions.

What gas do plant give off after photosynthesis?

In general outline, photosynthesis is the opposite of cellular respiration. CO2+ H2O+sunlight ----> O2 + H2O +carbohydrates.
It uses carbon dioxide and the energy from sunlight to make carbohydrates and oxygen (a waste product from plants).

The energy used by most living organisms ultimately comes from the sun plants convert this light energy into chemical energy through photosynthesis plants are called what?

Plants are called producers because they produce their own food through the process of photosynthesis using sunlight as the source of energy. This chemical energy stored in plants is then transferred to other organisms when they are consumed.

How do accessory pigments differ in function from chlorophyll and how do they affect the appearance of algae and the depths at which algae can grow?

Accessory pigments absorb light at different wavelengths than does chlorophyll. This process tends to increase the range of depths at which algae can grow. For example, the reddish accessory pigments called phycobilins are especially good at absorbing the blue light found at great depths in the sea, allowing the algae that contain them to live in deep water. Because accessory pigments reflect different wavelengths of light than does chlorophyll, they give algae a wide range of colors.

How many oxygen atoms are needed to start photosynthesis reaction?

In the first step of photosynthesis, which is light-dependent, two water molecules are needed to start the reaction. Each water molecule contains two oxygen atoms, so a total of four oxygen atoms are needed.

What are corrugated products used for?

The vast majority of corrugated products are used to package non-durable goods, such as food products. In the late 1990s, for example, 77.7 percent of corrugated products were used to package non-durable goods.

Where does photosynthesis occur in a venus fly trap?

Photosynthesis in a Venus flytrap occurs in the chloroplasts of its cells, which are mainly concentrated in the green parts of the trap, like the lobes. These chloroplasts contain chlorophyll that enables the plant to capture sunlight and convert it into energy to make food.

What is the importance of transpiration in plants?

As water transpires from the leaves into the atmosphere it pulls on water that had osmotically entered the roots and thus water is puled all the way up the plant; from the roots to the leaves.

Transpiration is an essential evil in the plants which takes place during gaseous exchange.

When plants go through photosynthesis they provide animals with which?

Plants provide animals with oxygen as a byproduct of photosynthesis. This oxygen is essential for animals to carry out cellular respiration, which is the process that generates energy for their survival.

What will be the effect of too much carbon dioxide in the atmosphere to photosynthesis?

Too much carbon dioxide in the atmosphere can initially increase rates of photosynthesis, as it is a key component for the process. However, excessive levels of carbon dioxide can eventually lead to decreased photosynthetic efficiency, disrupting plant growth and potentially impacting ecosystems.
