Enzymes are the substances that play a major role in most chemical reactions in living systems. Enzymes are biological catalysts that speed up chemical reactions by lowering the activation energy needed for the reaction to occur. They are crucial for maintaining the processes necessary for life.

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.
In a cell where do chemical reactions take place?
Chemical reactions in cells primarily take place in the cytoplasm and within organelles such as the mitochondria, endoplasmic reticulum, and chloroplasts. These reactions involve complex pathways that break down nutrients to provide energy, synthesize molecules, and regulate cellular processes.
Do Enzymes speed up reactions?
Enzymes act as catalysts in living systems.
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.
Which part of the brain controls affection?
The limbic system, which includes the amygdala, hippocampus, and hypothalamus, plays a crucial role in processing emotions and regulating affection. Additionally, the prefrontal cortex is involved in the cognitive aspects of emotional processing, such as evaluating and expressing affection.
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 release energy in the form of heat to the surroundings, which is why they are classified as chemical reactions. This energy is typically in the form of heat, but could also be light or sound. Exothermic reactions involve breaking and forming chemical bonds, leading to a change in energy of the system.
What are chemical that can change the rates of chemical reactions in nonlivings system?
These chemicals are called catalysts.
When a chemical reactions takes place in an closed system?
Mass is constant.
What is a system of double membranes on which chemical reactions take place?
Mitochondria
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.
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 difference between chemical and physical property?
Chemical properties describe the behavior of a substance in reactions that result in the formation of new substances. Physical properties describe the characteristics of a substance that can be observed or measured without changing its chemical composition.
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.
What is the chemical substance such as a drug that makes a body's system less active?
Alcohol
Which occurs when the forward and reverse reactions occur at the same time?
Chemical equilibrium occurs when the forward and reverse reactions in a chemical system occur at the same time, resulting in no overall change in the concentrations of reactants and products. At equilibrium, the rates of the forward and reverse reactions are equal, and the system is said to be in a state of dynamic balance.
What is the general term that describes the chemical system reactions that go inside of the body to keep it alive?
Metabolism
