Lactase amylase cellulase are what type of molecules?
Lactase, amylase, and cellulase are enzymes. Enzymes are proteins that act as biological catalysts, speeding up chemical reactions in living organisms. Each of these enzymes plays a specific role in breaking down lactose, starch, and cellulose, respectively.
What reaction does the enzyme peroxidase catalyze?
Peroxidase is a group of enymes that are found in human cells that increases the amount of oxidation produced. Oxidation is actually quite bad for the human body because it produces free radicals when produced. These free radicals cause diseases in the body like heart disease. However, oxidation is also helpful to the body. In such cases as your liver, oxidation helps to remove the alcohol from your body at about one ounce per hour. Without oxidation, you liver could ended up being bloated with alcohol and cause severe damage that may even be fatal. Peroxidase enzymes are a large family of enzymes that typically catalyze a reaction of the form: ROOR' + electron donor (2 e−) + 2H+ → ROH + R'OH.
Some are used as electron donors or treatment of waste waters. Though the exact mechanism is unknown, they are known to increase a plant's defenses against pathogens. They have other uses as well.
The Krebs cycle, also known as the citric acid cycle, is a series of chemical reactions that generates energy by breaking down acetyl-CoA derived from carbohydrates, fats, and proteins. It produces high-energy molecules (e.g., NADH, FADH2) used in the electron transport chain to generate ATP, the cell's main energy source. It also produces carbon dioxide as a byproduct.
Proteins are made by ribosomes in the cells of living organisms through a process called protein synthesis. This process involves the translation of genetic information stored in DNA into a sequence of amino acids, which are then folded into the specific three-dimensional structure of a protein.
Difference between organic and inorganic substances?
In general organic compounds / substances / materials contain carbon atoms bonded with other atoms and/or those related to life. It is the chemistry of carbon containing compounds.
Inorganic is everything else and generally do not contain carbon (with some exceptions).
Biological study brought about?
Biological study has advanced our understanding of living organisms, their functions, and interactions with the environment. It has enabled the development of important scientific advancements such as gene editing, biotechnology, and the understanding of diseases. Additionally, biological research has contributed to conservation efforts, helping preserve biodiversity and ecosystems.
The lipids in the Cell membrane are arranged?
mieosis.
Pepsin is found in the stomach, and breaks down long-chain proteins into shorter amino acids, whilst lipase is secreted into the duodenum by the pancreas to break down fats into their constituent parts: fatty acids and glycerol.
One way to determine before a child is born whether it will have an inherited disease?
Genetic testing of the parents can help identify if they are carriers of the disease, which increases the risk of passing it on to their child. Pre-implantation genetic diagnosis (PGD) can also be done during in vitro fertilization to screen embryos for genetic diseases before implantation. Consultation with a genetic counselor can provide guidance on testing options.
Do men and women have the same hormones?
Easier to list the ones that are different. 98% of a human being is functionally identical for either sex. Men have a prostate gland, testes and a penis. Women have ovaries, uterus, and a vagina.
What's the same:
Eyes, lungs, heart, brain, liver, pancreas, kidneys, bladder, bones, skin, blood....
As I said, 98% of a human is unisex.
What is the biological significance of fats?
Fats are essential for providing energy, insulating and protecting organs, helping with the absorption of fat-soluble vitamins, and serving as a source of essential fatty acids that the body cannot make on its own. They also play a role in cell membrane structure and signaling in the body.
What is the final electron acceptor in photosynthesis?
The final electron acceptor in photosynthesis is NADP+ (nicotinamide adenine dinucleotide phosphate). NADP+ accepts electrons, along with hydrogen ions, from the electron transport chain in the thylakoid membrane, and is reduced to NADPH, which is a key molecule in the production of carbohydrates during the light-independent reactions of photosynthesis.
What joins molecules by removing water?
A condensation reaction joins molecules by removing a water molecule. This process involves bonding two molecules together, with one molecule contributing a hydroxyl group (-OH) and the other contributing a hydrogen atom (-H).
Three Characteristics of Viruses that are characteristics of living things?
Viruses react to the environment, reproduce (through asexual means), and need energy to survive. They are also capable of passing hereditary information, but that could be included in reproduction.
The nitrogen base to which guanine bonds?
Guanine bonds with cytosine through three hydrogen bonds, forming a stable base pair in the DNA double helix.
What type of reaction joins two amino acids together?
When amino acids combine to form proteins or polypeptides a condensation reaction occurs. The carboxyl group of one molecule reacts with the amine group of the other molecule. One molecule of water is released and this results in C(O)NH, or a peptide bond.
Condensation is the reaction: the opposite process is termed Hydrolysis.
What kind of epithelial tissue is characterized by being only one cell layer thick?
Simple
For example, simple cuboidal epithelium
A layered version would be Stratified cuboidal epithelium
What are Cells with a full set of chromosomes called?
diploid, definition is here http://www.bioethics.gov/reports/stemcell/glossary.html
How does temperature change the action of enzymes?
Temperature can affect enzyme activity because enzymes work best within specific temperature ranges. At low temperatures, enzyme activity decreases as the molecules move more slowly, decreasing the likelihood of enzyme-substrate collisions. At high temperatures, enzyme activity can be disrupted because the enzyme structure can become denatured, leading to a loss of function. Optimal temperature for enzyme activity varies depending on the specific enzyme.
Describe in detail the appearance of a onion cell under HIGH power?
Cell boundaries (distinct black lines between the cells), and the stained cytoplasm are visible at 10 (ocular magnification) by 5 (stage magnification). The cells are very small at this point. At 10 by 10 cells are bigger and the vacuoles can be seen clearly as separate parts. Any other organelles cannot be seen by a low power microscope. As far as I remember nuclei cannot be seen in the case on onion epidermis. However, i am not too sure.
What is the function of rought endoplasmic reticulum?
To modify proteins, basically. To place simple carbohydrates on the proteins and give the protein and the chaperon's that fold them a place protected to do their work. Also ships the protein for further modification to the Golgi body.
How is starch broken down to glucose prior to glycolysis?
Starch occurs in two forms, alpha-amylose and amylopectin. Each may be enzymatically hydrolyzed: a-amylose by a-amylase [a(1-4)-glucan 4-glucanohydrolase], present in saliva and pancreatic juice; or by beta-amylase [a(1-4)-glucan maltohydrolase.
The a- and b-amylases also 'attack' amylopectin. Polysaccharides of intermediate length thusly formed are called dextrins.
