What substances does photosynthesis produce?
Photosynthesis produces glucose, which is a type of sugar that serves as the main source of energy for plants and other organisms. Additionally, during the process, oxygen is released as a byproduct into the atmosphere.
Which organelle may store water needed chemicals wastes and pigments in plant cells?
The vacuole is the organelle that may store water, chemicals, wastes, and pigments in plant cells. It helps in maintaining turgidity and storing essential nutrients and compounds for the plant's growth and survival.
What kind of chemical is carbohydrase is and what does it do?
Carbohydrase is am enzyme (biochemical catalyst) which help the decomposition of carbohydrates in simple sugars.
What is the process by which plants convert carbon dioxide into energy rich carbon compounds?
Plants convert carbon dioxide into energy-rich carbon compounds through the process of photosynthesis. This process involves capturing sunlight energy to convert carbon dioxide and water into glucose (a sugar) and oxygen. The energy stored in glucose is used by the plant for growth, reproduction, and other cellular processes.
What is the substance that dirties the air water and ground?
Pollution, which can be caused by various substances such as chemicals, particulate matter, and waste materials, is responsible for dirtying the air, water, and ground. Examples include carbon dioxide from burning fossil fuels, toxic chemicals from industrial processes, and plastic waste from improper disposal.
What are some characteristics of melanin?
Melanin is a pigment produced by melanocytes in the skin, hair, and eyes. It provides protection against UV radiation, determines skin color, and helps in wound healing and immune responses. Melanin levels vary among individuals based on genetic factors and exposure to sunlight.
Dr. Juan Salcedo was born in PAsay City on September 23, 1904. He invented the vitamin B1 combant mosquito malaria disease.
----- hope this information help to you --- ---- just email me if u need more something --- ^_^ geHOLic ^_^
Is vitamin A soluble in hexane?
Yes, vitamin A is soluble in hexane because it is a fat-soluble vitamin. Hexane is a non-polar solvent that can dissolve non-polar substances like fats and oils, making it suitable for dissolving vitamin A.
Why is sodium hydrogen carbonate important in cooking?
Sodium hydrogen carbonate, also known as baking soda, is important in cooking because it reacts with acidic ingredients to produce carbon dioxide gas, which helps baked goods rise and become light and fluffy. It can also be used as a leavening agent in recipes that do not contain any acidic ingredients. Additionally, it helps neutralize overly acidic flavors in dishes.
What are the membrane-bound sacs the Golgi complex packs proteins and other materials into?
The Golgi complex packs proteins and other materials into membrane-bound sacs called vesicles. These vesicles can then transport the packaged materials to different parts of the cell or outside of the cell.
The chemical formula for glass is not a fixed one, as it can vary based on the type of glass. However, one common type of glass is soda-lime glass, which has the general formula of SiO2 - Na2O - CaO.
What does the name of an enzyme tell us?
The name of an enzyme typically indicates its substrate or the type of reaction it catalyzes. Enzyme names often end in "-ase" to show that it is an enzyme. Additionally, the name may provide information about the enzyme's source or origin, such as "pepsin" from the stomach.
What does a DNA nucleotide consist of?
deoxyribose sugars, which are bonded to a phosphate group and a nitrogenous base
Very useful little critters, they are basically a nitrogenous base, a five-carbon sugar, and one to three phosphate groups (mono- to tri-phosphate). A very good article in the link below.
What is DNA and where is it found?
DNA (deoxyribonucleic acid) is a molecule that contains the genetic instructions for the development, functioning, growth, and reproduction of all living organisms. It is found within the cell nucleus of most living organisms, organized into structures called chromosomes. Each organism's DNA is unique and carries the hereditary information that is passed on from parent to offspring.
How do animals obtain many of is coenzymes?
Animals obtain many of their coenzymes through their diet. Coenzymes are essential organic molecules that assist enzymes in carrying out various metabolic processes in the body. These coenzymes are often derived from vitamins and other nutrients found in food sources.
What is the first protein structure to be determined?
The first protein structure to be determined was myoglobin, in 1958. Myoglobin is a heme-containing protein found in muscle cells which stores oxygen. Its structure was determined by John Kendrew and colleagues using X-ray crystallography.
No it hold all genetic material.

What are disadvantages of enzymes?
1. They are highly sensitive to changes in physical and chemical conditions surrounding them, therefore, it is hard for mankind to use them.
2. They are easily denatured by even a small increase in temperature and are highly susceptible to poisons and changes in pH. Therefore, the conditions in which they work must be tightly controlled.
3. Enzymes make our works harder when using them as the enzymes substrate mixture must be uncontaminated with other substances that might affect the reaction.
4. The high cost of enzyme isolation and purification discourages their use, especially in areas which currently have an established alternative procedure.
Does Myoglobin have a primary structure?
Yes, myoglobin does have a primary structure, which refers to the linear sequence of amino acids that make up the protein molecule. This primary structure is important for determining the unique function of myoglobin.
What chemicals denature proteins?
Denaturants such as urea, SDS, guanidium hydrochloridecan denature proteins. Organic solvent such as alcohol can be also used to denature proteins. A combination of reducing agent DTTor beta-mercaptoethaol with heating at 90 degrees for 5 minutes about will completely kill the three dimensional structure of proetin and make it to its primary structure.
What organic compounds are enzymes made up of?
Enzymes are Protein in Nature. Proteins are more precisely described as biochemical compounds. Some enzymes are combined with Rna's to form for example - Ribozymes.
Enzymes, while completely composed from Organic Protein, are 'merely' one Form of Protein.
What does galactose and fructose make?
Galactose and fructose can combine to form lactulose through a chemical reaction known as the Maillard reaction. This reaction occurs when reducing sugars such as galactose and fructose react with amino acids under heat, creating a browning effect and producing compounds with sweet tastes and potential health benefits.
