Is a toasted bread an irreversible change?
Yes, toasting bread is an irreversible change because the physical and chemical properties of the bread change permanently due to the application of heat. The process causes the bread to undergo a chemical reaction known as the Maillard reaction, which results in the browning and change in texture of the bread.
When the bonds of a protein are broken either by excessive heat or pH it is known as what?
When the bonds of a protein are broken by excessive heat or pH, it is known as denaturation. Denaturation disrupts the protein's structure and changes its properties, often causing it to lose function.
What causes water to condense in the atmosphere?
Water condenses in the atmosphere when warm air rises and cools, causing the water vapor in the air to change into liquid droplets. This process is known as condensation.
Why is it heating a platinum wire in air is a physical change?
Heating a platinum wire in air is a physical change because it does not change the chemical composition of the platinum wire. The heat causes the platinum wire to expand and may change its physical appearance, but it remains chemically the same.
What is a protein monomer?
A protein monomer is an individual unit that makes up a protein molecule. It consists of a sequence of amino acids linked together by peptide bonds. Proteins are made up of one or more of these monomers, known as polypeptide chains.
A genetic mutation that causes a codon that should code for a specific amino acid to be changed into a stop codon results in a shortened protein product and is known as?
A premature stop codon mutation, also known as a nonsense mutation. This mutation causes the translation of the protein to be halted prematurely, leading to a truncated and often nonfunctional protein product.
What ion initiates muscle contraction?
Calcium ions initiate muscle contraction by binding to the protein complex known as troponin, which then causes a conformational change in the protein tropomyosin. This conformational change exposes the active sites on actin filaments, allowing myosin cross-bridges to bind and initiate the muscle contraction process.
What produces protein and is known as the protein factory?
The "Protein Factories" in the cell are known as Ribsome.
What is the permanent change in the structure of a protein?
A permanent change in the structure of a protein is known as denaturation. This alteration disrupts the protein's native shape and can be caused by factors such as heat, pH changes, or chemical exposure, leading to loss of function. Denaturation is usually irreversible.
What is the bent or kinked form of retinal is combined with a protein called?
The bent or kinked form of retinal combined with a protein is known as rhodopsin. Rhodopsin is a light-sensitive receptor protein found in the rods of the retina, which is essential for vision in low-light conditions. When light hits rhodopsin, it causes a conformational change in retinal, triggering a signal that leads to visual perception.
What causes sunshine fluctuations?
It is known that the ageing of the glass ball the sun causes sunshine fluctuations. Also the can change the instruments and the location that is been recorded.
What are the mutations in the G protein that causes Pseudohypoparathyroidism?
The mutations are in the Gs-alpha subunit ( for example, Arg485 to His) and leads to pseudohypoparathyroidism, also known as Albright Hereditary Osteodystrophy.
What is the variable that causes a change in another variable?
An independent variable is the variable that causes a change in another variable, known as the dependent variable. The independent variable is manipulated or controlled in an experiment to observe its effect on the dependent variable.
Does Meat contain carbohydrates?
Protein is the most known vitamin. (there are probably more but protein is most known)
What causes a wave to bend from 1 medium to another?
A wave bends when it enters a new medium due to a change in its speed caused by the change in the medium's properties, such as density or elasticity. This change in speed at the boundary between the two mediums causes the wave to change direction, known as refraction.
What is the region called on a globular protein that can slightly change shape to fit a substrate during a catalysed reaction?
This regions is known as the active site.
What is the medical term meaning high urine protein levels?
Proteinuria is the medical term for excess protein in the urine.Anything in the urine ends with the word -uria. Protein is simply protein, therefore protein in the urine is "proteinuria".Other examples include blood in the urine (haematuria) and glucose in the urine (glycosuria).Anything in the urine ends with the word -uria.
