Are antibodies proteins that catalyze chemical reactions without being physically altered?
No, antibodies are not proteins that catalyze chemical reactions without being physically altered. Antibodies are proteins produced by the immune system to help recognize and neutralize foreign substances, such as bacteria and viruses. Enzymes are proteins that catalyze chemical reactions without being physically altered.
Do Enzymes speed up reactions?
Enzymes act as catalysts in living systems.
What role do enzymes play in the digestive system?
Enzymes in the digestive system help break down food into smaller molecules that can be absorbed by the body. They speed up chemical reactions that aid in the digestion and absorption of nutrients.
In a cell where do chemical reactions take place?
Chemical reactions in a cell primarily take place within the cytoplasm and organelles such as the mitochondria, endoplasmic reticulum, and chloroplasts. The cytoplasm is where most metabolic reactions occur, including glycolysis and protein synthesis. Organelles like the mitochondria are responsible for cellular respiration, while the chloroplasts are involved in photosynthesis. These reactions are essential for the cell to generate energy, produce biomolecules, and maintain homeostasis.
How do you use the word 'enzymes' in a sentence that clearly explains its meaning?
In the digestive system long chains of molecules are broken down into small units by the action of enzymes.Enzymes is a plural noun, so it can be used like this.Enzymes are found in saliva.
What is importance of enzyme?
They carry out chemical reactions to the cells and breaks down things to be digested. They also allow many chemical reactions to occur within the homeostasis constraints of a living system.
Why are exothermic reactions chemical reactions?
Exothermic reactions are chemical rections since these affects the composition and chemical properties of a matter and result in the formation of new substance. Example burning of coal , electrolysis of water.
What are chemical that can change the rates of chemical reactions in nonlivings system?
These chemicals are called catalysts.
What is the significance of negative reduction potential in the context of chemical reactions?
The negative reduction potential indicates the tendency of a substance to gain electrons in a chemical reaction. It is significant because substances with more negative reduction potentials are more likely to be reduced (gain electrons) and act as electron acceptors in reactions. This helps determine the direction and feasibility of reactions in a system.
What is a system of double membranes on which chemical reactions take place?
Mitochondria
When a chemical reactions takes place in an closed system?
Mass is constant.
What is true about chemical reactions in a closed system?
In a closed system, matter cannot enter or leave the system, but energy can still be exchanged with the surroundings. Chemical reactions in a closed system will reach equilibrium, where the rates of the forward and reverse reactions are equal and the concentrations of reactants and products remain constant. The total amount of matter in the system will not change during a reaction in a closed system.
What is the difference between chemical and physical property?
A chemical property is any of a material's properties that becomes evident during a chemical reaction; that is, any quality that can be established only by changing a substance's chemical identity. Simply speaking, chemical properties cannot be determined just by viewing or touching the substance; the substance's internal structure must be affected for its chemical properties to be investigated.A physical property is any measurable property the value of which describes a physical system's state at any given moment in time. For that reason the changes in the physical properties of a system can be used to describe its transformations (or evolutions between its momentary states).
What is the relationship between exothermic reactions and entropy changes in a chemical system?
In a chemical system, exothermic reactions release heat energy, while entropy changes refer to the disorder or randomness of molecules. Exothermic reactions typically lead to an increase in entropy, as the released heat energy can increase the movement and randomness of molecules in the system.
Where do chemical reactions occur in organic molecules?
Most chemical compounds do not combine with one another automatically, nor do chemical compounds break apart automatically. The great majority of the chemical reactions that occur within living things must be energized. This means that the atoms of a molecule must be separated by energy put into the system. The energy forces apart the atoms in the molecules and allows the reaction to take place.
What is the role of a redox buffer in maintaining the balance of electron transfer reactions in a chemical system?
A redox buffer helps to maintain the balance of electron transfer reactions in a chemical system by accepting or donating electrons as needed. This helps to stabilize the system and prevent excessive buildup of reactive species, ensuring that the reactions proceed smoothly and efficiently.
What are two effects caused by a chemical change?
Two effects that are caused by a chemical change are changes from one substance into another. Another effect that can be caused by a chemical change is a change in the temperature of the surrounding system and substance, or a change in color of the substance.
