Physical Reaction: Your teeth grind up the food, which thus changes the food's physical shape
Chemical Reaction: Enzymes in your saliva begin the digestion process by breaking down food particles so the stomach may digest it further; the hydrochloric acid in your stomach breaks the food down further so that the nutrients in the food may be absorbed into your blood stream; nutrients absorbed by blood are then converted into energy.

How are nuclear reactions and chemical reactions alike?
Nuclear reactions and chemical reactions both involve changes to atoms and their components, but they differ in the processes and energies involved. In both types of reactions, bonds are formed or broken, leading to the transformation of substances. Additionally, both reactions can release or absorb energy; however, nuclear reactions typically release much more energy due to changes in the nucleus, while chemical reactions usually involve electron interactions. Ultimately, both processes are fundamental to understanding matter and energy transformations in nature.
Light released during chemical reactions is called what?
Light released during chemical reactions is called "chemiluminescence." This phenomenon occurs when chemical energy is converted into light energy, often seen in reactions involving certain chemicals or bioluminescent organisms. Chemiluminescence is commonly used in applications like glow sticks and certain types of scientific assays.
Compare and contrast between exergonic and endergonic reactions?
Exergonic vs. Endergonic reactions: exergonic release more energy than they absorb. Endergonic reactions absorb more energy than they release.Exergonic reactions release energy while endergonic reactions absorb energy.
Are covalent and ionic bonds broken and formed in chemical reactions?
Yes, covalent and ionic bonds are both broken and formed during chemical reactions. In a reaction, reactant molecules undergo bond breaking, which requires energy, and the formation of new bonds in the products, which releases energy. This transformation is key to the rearrangement of atoms and the creation of new substances. Overall, the process involves the interplay of both types of bonds depending on the nature of the reactants and products involved.
How do enzymes in your body make chemical reactions occur at safe tempertuare?
Enzymes lower the activation energy of certain types of reactions. Because energy is directly related to heat, a lower activation energy corresponds to lower heat.
What type of chemical reaction occurs spontaneously?
Spontaneous chemical reactions are those that release energy and result in a decrease in free energy. They typically involve exothermic reactions where the products are more stable than the reactants, leading to a natural tendency for the reaction to occur without the input of additional energy. Examples include combustion reactions and some types of oxidation-reduction reactions.
Two types of chemical reactions?
Two kind of chemical reactions are exothermic and endothermic reactions. An exothermic reaction is one that releases energy. An endothermic reaction is one that absorbs energy. Hope this helps!! :)
Where energy is given off?
Energy is given off during exothermic reactions, where the system releases heat to the surroundings. Examples include combustion reactions, neutralization reactions, and some types of nuclear reactions.
Compare and contrast between exergonic and endergonic reactions?
Exergonic vs. Endergonic reactions: exergonic release more energy than they absorb. Endergonic reactions absorb more energy than they release.Exergonic reactions release energy while endergonic reactions absorb energy.
What is the difference between exothermic and exergonic reactions?
An exothermic reaction releases heat energy to the surroundings, while an exergonic reaction releases free energy. Both types of reactions involve the release of energy, but exothermic reactions specifically involve the release of heat.
What change releases energy into its surroundings?
Exothermic reactions release energy into their surroundings. These reactions involve the release of heat, light, or sound, resulting in a temperature increase in the surrounding environment. Examples include combustion, oxidation reactions, and many types of chemical reactions.
The total of all chemical reactions in an organism?
Metabolism is the total of all chemical reactions that occur within an organism, including processes like energy production, growth, repair, and waste elimination. These reactions are regulated by enzymes and can be categorized into two main types: catabolic reactions that break down molecules to release energy, and anabolic reactions that build molecules using energy.
All of the chemical reactions of the cell are called?
The chemical reactions of the cell are called metabolism. Metabolism consists of two main types of reactions: catabolic reactions, which break down molecules to release energy, and anabolic reactions, which build molecules using energy. These reactions are essential for the cell to function and maintain life.
How do enzymes in your body make chemical reactions occur at safe tempertuare?
Enzymes lower the activation energy of certain types of reactions. Because energy is directly related to heat, a lower activation energy corresponds to lower heat.
How is energy involved in a chemical reaction?
Activation energy is needed to start a chemical reaction. This energy is used to join the reactants together or break them apart. If a reaction is exothermic then it gives energy out. If it is endo thermic then the reaction takes energy in.
What are the two types of resiration?
The two types of respiration are aerobic respiration, which occurs in the presence of oxygen and produces more energy, and anaerobic respiration, which occurs in the absence of oxygen and produces less energy.
What are the different types of conventional sources of energy?
Fossil energy. Nuclear energy. Water, energy, wind energy, renewable energy like solar energy. The energies of the reactions caused by chemical waste.
