Chemical reactions in living organisms are triggered by various factors, including enzymes, temperature, pH levels, and the presence of specific molecules or ions. Enzymes are particularly important as they act as catalysts by lowering the activation energy needed for the reaction to occur. Additionally, external stimuli such as stress or injury can also trigger chemical reactions within living organisms.

Do Chemical reactions only occur in living organisms?
No, chemical reactions occur in both living and non-living systems. In living organisms, chemical reactions are essential for metabolic processes, while in non-living systems, chemical reactions can occur in various environments such as inorganic chemical reactions in the environment.
What best describes a stimulus?
A stimulus is something that causes a response in an organism, such as a change in the environment that triggers a reaction. It can be internal or external and can be physical, chemical, or biological in nature. Stimuli play a crucial role in triggering behaviors and adaptations in living organisms.
What is the difference between chemiluminescence and bioluminescence?
Chemiluminescence is the emission of light resulting from a chemical reaction without the involvement of living organisms, while bioluminescence is the production of light by living organisms through a chemical reaction typically involving an enzyme called luciferase. In essence, chemiluminescence is chemical-based light production, whereas bioluminescence is light produced by living organisms.
What do chemical reactions in living organisms need to start?
Chemical reactions in living organisms require a source of energy to start. This energy is typically obtained from molecules such as ATP. Additionally, enzymes play a critical role in catalyzing these reactions by lowering the activation energy required for the reaction to occur.
Is a catalyst a compound that makes up a living organism?
No, a catalyst is not a compound that makes up a living organism. A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process. Living organisms are made up of various compounds like proteins, lipids, carbohydrates, and nucleic acids.
Which chemical reaction carried out by all living organisms releases carbon dioxide from cells?
Respiration.
What is the main reason for chemical weathering?
A chemical reaction of the rock with water, air components, residues from living organisms, interaction of minerals.
What is the scientific term for the production of light by living organisms?
The scientific term for the production of light by living organisms is bioluminescence. It is a chemical reaction within the organism that generates light, commonly seen in marine animals like fireflies and certain types of fish.
Are living organisms mechanical or chemical?
Chemical :P
Substances that promote chemical reactions in living things but not affected by the reaction are?
enzymes. Enzymes are biological catalysts that increase the rate of chemical reactions in living organisms without being consumed in the process. They help lower the activation energy required for a reaction to occur.
Is rust living or nonliving?
Not living, it is a chemical reaction.
What branch of chemistry is concerned with living organisms?
Biochemistry is the branch of chemistry that is concerned with the chemical processes and substances that occur within living organisms. It focuses on studying the structure, function, and interactions of biological molecules such as proteins, nucleic acids, carbohydrates, and lipids.
What is bioluminous means?
Bioluminescence is the production and emission of light by living organisms, such as certain fish, insects, and microorganisms. These organisms possess special molecules that produce light through a chemical reaction.
Is living organisms mechanical or chemical?
Both, but mostly chemical.
Do Chemical reactions only occur in living organisms?
No, chemical reactions occur in both living and non-living systems. In living organisms, chemical reactions are essential for metabolic processes, while in non-living systems, chemical reactions can occur in various environments such as inorganic chemical reactions in the environment.
What best describes a stimulus?
A stimulus is something that causes a response in an organism, such as a change in the environment that triggers a reaction. It can be internal or external and can be physical, chemical, or biological in nature. Stimuli play a crucial role in triggering behaviors and adaptations in living organisms.
What is the definition of bio luminescence?
Bioluminescence is the production and emission of light by living organisms as a result of a chemical reaction. It is a form of light production that occurs in many marine organisms, such as jellyfish and certain fish species, as well as some insects and fungi.
