Compare mechanical digestion to chemical digestion?
mechanical digestion - chewing, mixing, churning chemical digestion - breakdown of fat, carbohydrate and proteins by specific enzymes (lipases, amylases, and proteinases respectively)
Are chemical reactions a chemical change of original substances before a chemical reaction takes a place?
Chemical reactions involve the breaking and forming of chemical bonds in the original substances, resulting in a chemical change. Before a chemical reaction occurs, the original substances have specific chemical properties that undergo transformation during the reaction. The reactants interact to form new products with different chemical compositions.
Do antibiotics have any chemical substances?
The definition of a chemical substance is a material with a specific chemical composition. So yes, antibiotics contain chemical substances. Although, antibiotics will employ some sort of living microorganism, instead of just one simple chemical substance.
What is the purpose of chemical digestion what is responsible for the rate of chemical digestion?
The purpose of chemical digestion is to break down complex food molecules into simpler, absorbable nutrients, such as amino acids, fatty acids, and simple sugars, which can then be utilized by the body for energy, growth, and repair. Enzymes play a crucial role in this process, as they catalyze the breakdown of food substances, and their activity is influenced by factors such as temperature, pH levels, and the presence of specific substrates. Additionally, the surface area of the food particles and the overall efficiency of the digestive system can also affect the rate of chemical digestion.
What is a way in which chemical properties are used?
Chemical properties are used in various ways, such as identifying substances through chemical reactions, predicting reactivity with other substances, determining the suitability of materials for specific applications, and understanding the behavior of substances under different conditions.
Does a chemical formula describes a chemical reaction?
Yes, chemical equations describe chemical reactions. A chemical equation tells you what substances are reacting, what substances are produced and, in a balanced equation, provides the coefficients to tell us in what ratio the substances react or are produced.
Is Chemical Abstracts Service for specific single chemical?
Chemical Abstracts Service (CAS) is a division of the American Chemical Society that provides databases containing comprehensive information on chemical substances. It covers a wide range of chemicals, including organic and inorganic compounds, polymers, and biological substances, rather than focusing on a single specific chemical. CAS assigns a unique identifier, known as a CAS Registry Number, to each chemical substance to facilitate accurate identification.
What is the difference between atoms compounds minerals?
Minerals are solid homogeneous inorganic substances having a specific chemical composition that can be represented by a chemical formula. They are different from rocks, which can be a mixture of minerals and non-minerals and do not have a specific chemical composition.
Is 1865 sg 350-22 chemical properity?
1865 SG 350-22 is not a specific chemical compound or substance, so it does not have inherent chemical properties. Chemical properties are characteristics that describe how a substance reacts or changes into new substances; a specific chemical formula or name is needed to determine these properties.
Does a compound have a chemical composition?
Yes
Are compounds of the element?
The elements of a compound are the chemical bonds that are present in a specific ratio in a compound. Elements are pure chemical substances that are made of the same atom.
Explain why chemical digestion does not begin in the mouth for all foods?
Chemical digestion in the mouth primarily involves the breakdown of carbohydrates by the enzyme amylase in saliva. Not all foods require significant carbohydrate digestion, such as proteins and fats. Therefore, chemical digestion for these macronutrients begins further down the digestive tract, where specific enzymes like pepsin and lipase are present.
