Which one of the properties of life describes the sum or total of all biochemical reactions occurring within an organism?
Metabolism
The sum total of the biochemical reactions occurring in an organism is called its metabolism.
What term refers to chemical reactions that release energy ?
Chemical reactions that release energy, usually in the form of heat, are called exothermic reactions. Chemical reactions that absorb energy, usually in the form of heat, are called endothermic reactions.
What is anabolism and catabolism?
Anabolism requires energy to grow and build. Catabolism uses energy to break down. These metabolic processes work together in all living organisms to do things like produce energy and repair cells.
What is catabolic and anabolic?
Anabolism and catabolism are the two broad classes of biochemical reactions that make up metabolism. Anabolism is the synthesis of complex molecules from simpler ones. These chemical reactions require energy. Catabolism is the breakdown of complex molecules into simpler ones. These reactions release energy.
What do you mean by metabolism?
Metabolism is the process by which your body converts what you eat and drink into energy. During this complex process, calories in food and beverages are combined with oxygen to release the energy your body needs to function.
What term refers to chemical reactions that release energy?
Chemical reactions that release energy are called exothermic. In exothermic reactions, more energy is released when the bonds are formed in the products than is used to break the bonds in the reactants. Exothermic reactions are accompanied by an increase in temperature of the reaction mixture.
When molecules are being built by chemical reactions it is called?
In a chemical reaction, the atoms and molecules that interact with each other are called reactants. In a chemical reaction, the atoms and molecules produced by the reaction are called products.
What is the reaction of a living organism to a stimulus called?
The ability of an organism to respond to external stimuli is called sensitivity. For example, Plants grow towards light(external stimuli) sources, and if the direction of light is changed, the plant will also change its direction of growth to accommodate for survival. So, the correct answer is ‘Sensitivity’.
Why are chemical reactions important to living organisms?
Chemical reactions are crucial for our cells to make energy, or ATP. All living things need energy to survive and ATP is actually a reactant that drives many other chemical reactions inside cells. Cells use a process called cellular respiration to make energy.
What is a chemical equation ?
Chemical Equation. A combination of symbols and chemical formulas used to describe what happens in a chemical reaction. The equation identifies the reactants and resulting products. Coefficient. A number written in front of a chemical formula to show how many molecules of that substance are present.
What are reactants in a chemical reaction ?
What are the reactants and products in a chemical reaction? The reactants are the substances that start the chemical reaction. The products are the substances that are produced in the chemical reaction.
What does it mean for a chemical reaction to be balanced?
To balance a reaction means to make the number of atoms the same on both the reactants and products side. To do so, coefficients need to be added to the chemical equation.
Which is a chemical reaction?
Chemical reactions involve breaking chemical bonds between reactant molecules (particles) and forming new bonds between atoms in product particles (molecules). The number of atoms before and after the chemical change is the same but the number of molecules will change.
What is chemical reaction in simple words?
Definition of chemical reaction
: a chemical change that occurs when two or more substances combine to form a new substance.
What is energy metabolism?
Energy metabolism is the process of generating energy (ATP) from nutrients. Metabolism comprises a series of interconnected pathways that can function in the presence or absence of oxygen. Aerobic metabolism converts one glucose molecule into 30-32 ATP molecules.
Which term means the study of the molecules and chemical reactions that occur in living cells?Biochemistry. the study of the molecules and chemical reactions that occur in living cells. Describe a decomposition reaction: breaks down a large molecule into smaller parts.
Which term is used specifically to describe the addition of an inorganic phosphate to an organic molecule?
Phosphorylation. Addition of an inorganic phosphate (pi)group to an organic molecule.
What is ghrelin ?
Ghrelin, the “hunger hormone” is a peptide produced by ghrelin cells in the gastrointestinal tract which functions as a neuropeptide in the CNS. Beyond regulating hunger ghrelin also plays a significant role in regulating the distribution and rate of use of energy. When the stomach is empty ghrelin is secreted .
Which best defines the term nutrient?
nutrient. noun. Definition of nutrient (Entry 2 of 2) : a substance or ingredient that promotes growth, provides energy, and maintains life Tomatoes contain a lot of nutrients, among them vitamins C and B-complex and the minerals iron and potassium.
Which type of reaction is anabolic?
Endergonic reactions
Endergonic reactions in organisms are called anabolic reactions. These reactions absorb energy and build bigger molecules from smaller ones. An example of an anabolic reaction is the joining of amino acids to form a protein.
What is chemical reaction in biology?
chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products. Substances are either chemical elements or compounds. A chemical reaction rearranges the constituent atoms of the reactants to create different substances as products.
What is the enzyme?
Enzymes are proteins that help speed up metabolism, or the chemical reactions in our bodies. They build some substances and break others down. All living things have enzymes. Our bodies naturally produce enzymes.
What are the chemical reactions in the body?
Within biological systems there are six major classes of biochemical reactions that are mediated by enzymes. These include group transfer reactions, the formation/removal of carbon-carbon double bonds, isomerization reactions, ligation reactions, hydrolysis reactions, and oxidation-reduction reactions.
What does the process known as anabolism refer to Mcq?
Anabolism collectively refers to all the processes of chemical reactions that build larger molecules out of smaller molecules or atoms; these processes are also known as anabolic processes or anabolic pathways.
What is metabolism Class 9?
Metabolism is a term that is used to describe all chemical reactions involved in maintaining the living state of the cells and the organism. Metabolism can be conveniently divided into two categories: Catabolism – the breakdown of molecules to obtain energy.
What does anabolic reaction mean?
anabolic reactions: reactions that build smaller molecules into larger molecules. biosynthesis reactions: reactions that create new molecules, also called anabolic reactions. catabolic hormones: hormones that stimulate the breakdown of larger molecules.
What is catabolism in biology class 11?
Catabolism is the break down of complex molecules. Catabolism is the breakdown of complex substances to their constituent parts (glucose, amino acids and fatty acids) which form substrates for metabolic pathways.
What is anabolism and catabolism Class 11?
Anabolism creates molecules the body needs for functionality and it uses energy in the process. Catabolism, on the other hand, breaks down complex molecules and releases energy which is available for the body to use. Read on to what is anabolism and catabolism and how are the two different from each other.
