Which organelle helps with photosynthesis?
The organelles where photosynthesis occurs are called Chloroplasts. Occuring only in plants, chloroplasts are small vesicle-like organelles that contain sacs of the pigment Chlorophyll. These sacs absorb sunlight to initiate the chemical reaction photosynthesis.
In Photosynthesis 6 molecules of carbon dioxide result in?
In photosynthesis, 6 molecules of carbon dioxide result in 1 molecule of glucose. Through the process of photosynthesis, carbon dioxide molecules are converted into glucose using energy from sunlight and releasing oxygen as a byproduct.
Why is photosynthesis considered an energy conversion reaction?
Photosynthesis converts light energy from the sun into chemical energy stored in glucose molecules. This process involves the conversion of light energy into chemical energy, making it an energy conversion reaction.
What Stage of photosynthesis is sugar is made?
Sugar is made during the Calvin cycle, which is the second stage of photosynthesis. In this stage, carbon dioxide is converted into glucose using energy from ATP and NADPH produced in the light-dependent reactions.
Why does potassium hydrogencarbonate encourage photosynthesis?
Potassium hydrogencarbonate provides a source of carbon dioxide that can be utilized during photosynthesis by plants. Carbon dioxide is a key component needed for photosynthesis to occur, as it is used by plants to create glucose and oxygen. By providing potassium hydrogencarbonate, we are essentially supplying plants with the necessary raw materials to carry out photosynthesis more effectively.
What are the resulting products of the splitting of water in photosynthesis?
Glucose sugar; enzymatic processes such as photosynthesis have highly predicable outcomes.
In chemistry the splitting of water results in (2) H2 and (1) O2, yet in biochemistry the splitting of water involves H+ and OH-.
Atp is formed when what enters the thylakoid lumen?
Within the thyakoid membrane, electrons from water are "excited" by photons of light energy in Photosystem II. The excited electrons "fall" from Photosystem II, pass through the electron transport chain (ETC) and flow into Photosystem I. As the electrons travel down the ETC, one molecole of hydrogen is pumped across the membrane from the stroma (fluid space inside the chloroplast) into the thylakoid where a higher gradient of H+. The ions pass onto the protien, ATP synthase which takes one H+ ion and pumps it through the membrane acting like a motor generating one molecule of ATP. The ATP is now located in the stroma and will be used shortly in the Calvin Cycle.
How much energy is produced in 1 glucose?
The metabolism of one molecule of glucose into two molecules of pyruvic acid through a process called glycosysis produces 2 ATP molecules
Which of the following best describes the direct mechanism of ATP production during photosynthesis?
The direct mechanism of ATP production during photosynthesis occurs through the process of photophosphorylation, specifically through the light-dependent reactions in the thylakoid membrane of the chloroplast. Here, ATP is produced through the generation and flow of protons across the membrane, driving the ATP synthase enzyme to produce ATP from ADP and inorganic phosphate.
Is vacuole a site of photosynthesis?
No, vacuoles are cellular organelles that play a role in storing nutrients, waste products, and maintaining turgor pressure within the cell. Photosynthesis primarily occurs in chloroplasts, a different organelle found in plant cells.
What does a porometer measure?
A porometer measures the pore size and distribution in a material, such as a membrane or filter. It is commonly used in scientific research and quality control to assess the permeability and characteristics of porous materials.
Where do the two stages of photosynthesis occur?
The second step of photosynthesis happens between the chloroplasts, rather than inside of them. This particular step is also independent of light, so if the light suddenly goes away for some reason, it doesn't totally stop the photosynthesis all at once.
Does green light affect plants?
Green light does affect plants, but it doesn't really provide much help in the plants' growth. Plants that are green absorb all the colors of light except the color green, which is reflected off the plant. This is why we see the plant as green.
How many molecules of ATP are made from aerobic cellular respiration?
Aerobic cellular respiration produces a total of around 36-38 molecules of ATP per glucose molecule. This occurs through a series of metabolic pathways, including glycolysis, the Krebs cycle, and oxidative phosphorylation in the mitochondria.
What membrane do light dependent reactions take place?
Light-dependent reactions in photosynthesis take place in the thylakoid membrane of chloroplasts. This membrane contains pigments such as chlorophyll that absorb light energy and convert it into chemical energy in the form of ATP and NADPH.
e) ATP is not made during any of the processes. ATP is produced in both glycolysis (2 ATP) and the electron transport chain (ETC) in cellular respiration. The Krebs cycle (citric acid cycle) produces some ATP indirectly through the generation of NADH and FADH2, which then feed into the ETC for ATP production.
Explain the importance of gemma cups to Marchantia sp?
Liverworts can also reproduce asexually by means of special structures called gemmae cups. These little cups can be easily seen on the surface of the plant. Each gemma cup contains a number of tiny plantlets called gemmae, and a single drop of water will disperse them. These little vegetative "clones" will then grow into a new gametophyte.
How does coal trace back to photosynthesis?
Coal comes from the remains of plants and trees that grew millions of years ago. These plants absorbed sunlight and converted it into energy through photosynthesis. Over time, the organic matter from these plants became buried, subjected to heat and pressure, eventually forming coal.
phloem. Phloem is a plant tissue that is responsible for transporting sugars, nutrients, and other organic compounds produced during photosynthesis from the leaves to other parts of the plant, such as the roots, stems, and fruits.
What reaction includes glucose and oxygen?
The reaction between glucose and oxygen is aerobic respiration, which occurs in living organisms to produce energy. In this process, glucose is broken down in the presence of oxygen to release carbon dioxide, water, and energy in the form of ATP.
A gas giant often has a thick atmosphere composed mainly of hydrogen and helium. These planets typically have no solid surface and may have many moons and planetary rings. They are much larger than terrestrial planets like Earth and are located farther from their host star.
All the carbon atoms in glucose are ultimately incorporated into carbon dioxide during cellular respiration. This process occurs through a series of metabolic reactions that break down glucose to produce energy, with carbon dioxide being a byproduct that is released as waste.
What gas given off by plants to the during photosynthetic process is needed by living things?
during photosynthesis plants take in carbon dioxide and give out oxygen
Where do all products of photosynthesis end up?
The products of photosynthesis, such as glucose and oxygen, are used by the plant for energy and growth. Excess glucose is stored as starch, while oxygen is released into the atmosphere through the plant's stomata.
Only a small amount of the light energy from the sun is used during photosynthesis because plants can only absorb specific wavelengths of light (mainly blue and red light) for the process of photosynthesis. Green light is reflected and not utilized. Additionally, not all the absorbed light energy is converted into chemical energy due to limitations in the efficiency of the photosynthetic process.
