Is digestion an exothermic reaction?

Digestion is actually an endothermic process because energy is required to break down food into smaller molecules for absorption. This energy is used to drive the chemical reactions that break down the macromolecules in food into smaller molecules that can be absorbed by the body.


Why is digestion an endothermic reaction?

Digestion is an endothermic process because it requires energy to break down food molecules into smaller components that can be absorbed by the body. The breaking of chemical bonds in food molecules and the synthesis of new molecules in the body require energy input to drive these processes.


Why photosynthesis is considered endothermic reaction?

Plants absorb sunlight and this heat is used for prepairing their food that's why its a exothermic reaction.


Is breathing an endothermic or exothermic reaction?

Breathing is an exothermic reaction. To explain clearly, during digestion food particles break down into smaller particles. These turn into glucose, this glucose combines with the oxygen present in the cell and provides energy. The special name of this reaction is respiration. It releases heat so it is an exothermic reaction.


Is the chemical reaction in flameless ration heaters classified as an endothermic or an exothermic reaction?

The chemical reaction in flameless ration heaters is classified as an exothermic reaction because it releases heat as a byproduct. The reaction involves the oxidation of a material such as magnesium, which produces heat that can warm up the food pouch.


When your body metabolizes food is it endothermic?

No, in most cases it isn't endothermic. Metabolism, based on the Krebs Cycle, is a biochemical reaction which creates Adenosine Triphosphate, also known as ATP and Energy. Energy is in fact exothermic.


By what process do living things get energy from food?

Living things get energy from food during digestion. This is an exothermic reaction in which heat and electrons are released and used as energy.


Is a thermos endothermic or exothermic?

Endothermic: absorbs energy from surroundings in the form of heat. ie. outside temperature loses heat. Exothermic: releases energy into surroundings in the form of heat ie. outside temperature gains heat. Seeing as a thermos is supposed to MAINTAIN the temperature of its contents, it is neither.


Is cold pack exothermic or endothermic?

Endothermic- a change in which energy is taken in. The melting of ice is an endothermic change. Ice absorbs thermal energy from its surroundings when it melts. That's why you pack drinks and food in an ice-filled picnic cooler to keep them cold. So yes an ice cube is endothermic.


Examples of endothermic and exothermic reactions?

Exothermic reactions give out energy overall. Here are some exothermic reactions:- Combustion of fuels such as hydrogen & methane- Neutralisation of an acid by an alkali- Reaction between sulphur & ironEndothermic reactions take in energy overall. Here are some endothermic reactions:- Reactions involved in cooking- The thermal decomposition of calcium carbonate- Photosynthesis in which plants use sunlight, carbon dioxide & water to make their own food


What side is heat on in an exothermic reaction?

Heat is released as a product in an exothermic reaction, so it is on the product side of the reaction.


What is the difference between endothermic and exothermic And give examples?

Chemical reactions that release energy in the form of heat, light, or sound are called exothermic reactions. Example: Mixture of sodium and chlorine to yield table salt In other words, combination reactions are exothermic. Reactions that absorb energy or require energy in order to proceed are called endothermic reactions. For example: In the process of photosynthesis, plants use the energy from the sun to convert carbon dioxide and water to glucose and oxygen.
