Chemical Reactions take place in our body too. ... For example, the whole digestion process involves chemical reaction of acids and the food. During digestion, the food is broken down in to smaller molecules. The salivary glands in our mouth release digestive enzymes which help in the breakdown of food.

Why digestion is a chemical reaction?

As food travels from your mouth into your digestive system, it's broken down by digestive enzymes that turn it into smaller nutrients that your body can easily absorb. This breakdown is known as chemical digestion. Without it, your body wouldn't be able to absorb nutrients from the foods you eat.

Is digestion physical or chemical?

Digestion is considered a physical and chemical change because enzymes in the stomach and intestines break down large macromolecules into simpler molecules so that the body can more easily absorb the food.

What is an example of physical digestion?

Examples of physical digestion, also known as mechanical digestion, are the act of chewing, as well as peristalsis in the stomach.

What are two examples of physical and chemical changes in the digestive system?

A physical change occurs in the components of the sandwich so your food can continue on its journey. Your teeth grind the components of the sandwich into manageable parts. Your saliva glands excrete spit, which helps break the chewed food down. Then, a chemical change occurs after your food is mixed with saliva.

What type of reaction is digestion?

Digestion of food in our body is a decomposition reaction.

What is the chemical equation of respiration?

C 6 H 12 O 6 + 6 O 2 --> 6 CO 2 + 6 H 2 O + ATP is the complete balanced chemical formula for cellular respiration.

What are the two types of digestion?

Digestion is a form of catabolism or breaking down of substances that involves two separate processes: mechanical digestion and chemical digestion. Mechanical digestion involves physically breaking down food substances into smaller particles to more efficiently undergo chemical digestion.

What are the 14 parts of digestive system?

The major parts of the digestive system:
  • Salivary glands.
  • Pharynx.
  • Esophagus.
  • Stomach.
  • Small Intestine.
  • Large Intestine.
  • Rectum.
  • Accessory digestive organs: liver, gallbladder, pancreas.

What is the correct order of digestion?

The main organs that make up the digestive system (in order of their function) are the mouth, esophagus, stomach, small intestine, large intestine, rectum and anus.

What is the process of digestion step by step?

Digestive Processes

The processes of digestion include six activities: ingestion, propulsion, mechanical or physical digestion, chemical digestion, absorption, and defecation. The first of these processes, ingestion, refers to the entry of food into the alimentary canal through the mouth.

What is the chemical equation of photosynthesis?

The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

What is the chemical reaction of aerobic respiration?

Aerobic respiration is the aerobic catabolism of nutrients to carbon dioxide, water, and energy, and involves an electron transport system in which molecular oxygen is the final electron acceptor. The overall reaction is: C6H12O6 + 6O2 yields 6CO2 + 6H2O + energy (as ATP).

What is respiration class 10th?

RESPIRATION is the biochemical process in living organisms involving the production of energy. This is typically done with intake of oxygen and this results in the release of carbon dioxide, water, and ATP (the currency of energy in cells).

Is digestion an exothermic reaction?

Digestion is an exothermic reaction. During the process of digestion complex substances such as starch carbohydrates and proteins are broken down into simpler form such as simple sugar and amino acids respectively. Since energy is produced in the process of digestion ,it is an exothermic reaction.

What is the primary type of chemical reaction involved in digestion?

ANSWER: The primary type of reaction involved in the 'digestion of a meal' by the 'digestive system' is a decomposition reaction. EXPLANATION: The food that is digested by the 'digestive system' gets decomposed or broken into smaller units.

What are the two main types of anaerobic respiration?

There are two main types of anaerobic respiration:
  • Alcoholic fermentation.
  • Lactic acid fermentation.

What are the three steps of aerobic respiration?

Aerobic respiration is divided into three main stages: Glycolysis, Citric acid cycle and Electron transport chain.

Is glycolysis aerobic or anaerobic?

Glycolysis is used by all cells in the body for energy generation. The final product of glycolysis is pyruvate in aerobic settings and lactate in anaerobic conditions. Pyruvate enters the Krebs cycle for further energy production.

What is the chemical equation of photosynthesis Class 7?

A simple word equation that can be used to describe the process of photosynthesis is carbon dioxide + water —> glucose + oxygen + water. A balanced chemical equation for the process can be written as 6CO2 + 6H2O —> C6H12O6 + 6O2.

What are the two chemical reactions in photosynthesis?

Light-dependent and light-independent reactions are two successive reactions that occur during photosynthesis.

Is carbon a cycle?

Carbon is the chemical backbone of all life on Earth. ... It's also found in our atmosphere in the form of carbon dioxide or CO2. The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again.

What are the six steps of the digestive system?

The six major activities of the digestive system are ingestion, propulsion, mechanical breakdown, chemical digestion, absorption, and elimination. First, food is ingested, chewed, and swallowed. Next, muscular contractions propel it through the alimentary canal and physically break it down into tiny particles.

What are the 10 steps of the digestive system in order?

The digestive processes are ingestion, propulsion, mechanical digestion, chemical digestion, absorption, and defecation.

Which best describes the physical and chemical digestion of food?

Which best describes the physical and chemical digestion of food? ... Physical and chemicall digestion occur in the small intestine; only chemical digestion occurs in the mouth. Only physical digestion occurs in the stomach; chemical and physical digestion occur in the large intestine.
