How are atoms and molecules affected by chemical reactions?
In a chemical reaction, atoms are rearranged and bonds between them are broken and formed to create new substances. Molecules can be broken down into smaller molecules or combined to form larger molecules through chemical reactions. Overall, chemical reactions alter the arrangement of atoms and molecules to create different substances with unique properties.
Which molecules facilitate chemical reactions in the body by reducing the reaction's activation energy?
Enzymes
Can you explain the diagram of molecules and how it relates to chemical reactions?
The diagram of molecules shows how atoms are arranged in a molecule. In chemical reactions, molecules interact and rearrange their atoms to form new substances. The diagram helps us understand how molecules change during a chemical reaction.
How does sulfuric acid work in chemical reactions?
Sulfuric acid is a strong acid that can donate protons in chemical reactions, making it a powerful catalyst. It can also act as a dehydrating agent, removing water molecules from compounds to facilitate reactions. Additionally, sulfuric acid can react with other substances to form new compounds, changing the chemical properties of the reactants.
How are new substances formed during chemical reactions?
Chemical bonds in the starting substances must break. molecules are always moving. if the molecules bump into each other with a enough energy, the chemical bonds in the molecules can break. the atoms then rearrange, and new bonds form to make new substances.
Which of the molecules in this chemical equation shown is a reactanct?
The molecules on the left side of the arrow in a chemical equation are the reactants. They are the starting substances that undergo chemical reactions to form products.
Blank Are the substances that speed up chemical reactions in the body?
Enzymes are the substances that speed up chemical reactions in the body by lowering the activation energy needed for the reaction to occur. They are biological catalysts that help facilitate various cellular processes.
Does chemical reactions create molecules and compounds?
Yes, chemical reactions can create new molecules and compounds by rearranging atoms in existing substances. This process involves breaking and forming chemical bonds to create different combinations of elements.
What are the large complex protein molecules that modify chemical reactions?
The large complex protein molecules that modify chemical reactions are called enzymes. Enzymes act as catalysts, speeding up chemical reactions by lowering the activation energy required for the reaction to occur. They bind to specific molecules called substrates and facilitate the conversion of substrates into products.
What type of reaction occurs when atom combine to form molecules or when molecules break down into atoms?
Chemical reactions occur when atoms combine to form molecules (synthesis reaction) or when molecules break down into atoms (decomposition reaction). These reactions involve the rearrangement of atoms to form new substances with different properties.
Which part of the cell membrane helps chemical reactions happen?
The proteins embedded in the cell membrane, such as enzymes and receptors, facilitate chemical reactions by serving as catalysts or by binding to specific molecules to initiate signaling cascades. These proteins play a crucial role in regulating the transport of substances in and out of the cell and in transmitting signals across the membrane.
What are formed by Chemical changes?
Chemical changes can result in the formation of new substances with different properties than the original substances. This can include the formation of new molecules, compounds, or materials through chemical reactions.
