Describe the role of energy in chemical reactions?
Energy is required to break bonds between atoms in reactant molecules, allowing them to rearrange into new products. This energy is called activation energy. Some reactions release energy, called exothermic reactions, while others absorb energy, called endothermic reactions. Overall, energy is essential for driving chemical reactions and determining whether they proceed or not.
How are anaerobic and aerobis reactions different?
Anaerobic reactions happen in the cytoplasm of a cell, Aerobic reactions occur in the mitochondria of a cell Anaerobic reactions do not require oxygen, Aerobic reactions do require oxygen
Do all reactions release energy?
No, not all reactions release energy. Some reactions require an input of energy to proceed, and these are called endothermic reactions. Endothermic reactions absorb heat from the surroundings rather than releasing it.
Can chemical reactions absorb energy?
Yes, chemical reactions can absorb energy. This can occur in endothermic reactions, where energy is required for the reaction to proceed. Examples include the reaction of baking soda and vinegar, which absorbs heat energy.
What name is given to all chemical reactions which releases heat energy?
Exothermic reactions produce heat. Endothermic reactions take in heat from the surrounding area and get cold.

Chemical reactions that consume free energy are called?
Exergonic reactions.
Chemical reactions that release energy do if occur or don't?
These are called exothermic reactions.
Do all reactions release energy?
No, not all reactions release energy. Some reactions require an input of energy to proceed, and these are called endothermic reactions. Endothermic reactions absorb heat from the surroundings rather than releasing it.
What chemical reaction release thermal energy?
only nuclear reactionsChemical reactions that release free energy are called exergonic reactions. Fire and cellular respiration are examples of exergonic reactions.
What are the reactions in which light energy from the sun is converted to chemical energy called?
light-dependent reactions. such as photosynthesis in green plants.
What is chemical reactions that consume free energy called?
Chemical reactions that consume free energy are called endergonic reactions. In these reactions, the change in Gibbs free energy is positive, indicating that the products have more free energy than the reactants. As a result, they require an input of energy to proceed. Examples include photosynthesis and the synthesis of complex molecules.
Which energy yielding nutrients lead to storage of body fat?
Any energy-yielding nutrients that are ingested in excess will be stored as body fat.
What is the type of chemical reaction in which heat energy is absorbed?
Endothermic reactions.Endo- means 'inside' which is where the energy ends up.Exothermic reactions give off energy. Exo- means 'outside'. Think that a spider sheds an 'exo'skeleton, or a skin on the outside.
Can chemical reactions absorb energy?
Yes, chemical reactions can absorb energy. This can occur in endothermic reactions, where energy is required for the reaction to proceed. Examples include the reaction of baking soda and vinegar, which absorbs heat energy.
