What are free radical reactions?
Free radical reactions involve molecules with unpaired electrons, making them highly reactive. These reactions can lead to chain reactions where a radical quickly reacts with another molecule to form a new radical. Free radicals are involved in various biological processes and environmental reactions.
Which kind of large biological molecule are enzymes?
Enzymes are proteins, which are a type of large biological molecule. They act as catalysts to accelerate chemical reactions in living organisms by lowering the activation energy required for those reactions to occur. Enzymes are highly specific, meaning each enzyme typically catalyzes only one type of reaction or a set of closely related reactions. Some enzymes may also contain non-protein components, such as cofactors or coenzymes, which assist in their catalytic function.
What are unique chemical groups confer special properties to an organic molecule called?
Unique chemical groups that confer special properties to an organic molecule are called functional groups. These groups determine how the molecule interacts with other substances, influencing its reactivity, solubility, and overall behavior in chemical reactions. Examples of functional groups include hydroxyl (-OH), carboxyl (-COOH), and amino (-NH2) groups. Each functional group imparts specific characteristics that are crucial for the molecule's role in biological systems.
What organic molecule always ends in -ASE?
an enzyme. although i dont know if an enzyme is an organic molecule
How do structure and function affect how molecules work?
structure
Of what biological significance is the DNA molecule?
The biological significance of a DNA molecule is that it: 1) Controls the synthesis of proteins (as well as enzymes because they are also proteins). 2) Is responsible for carrying hereditary characteristics.
When biological molecules engage in condensation such reactions?
When biological molecules engage in condensation reactions, they release a water molecule as a byproduct. These reactions are commonly involved in building larger molecules by linking smaller subunits together. Examples include the formation of peptide bonds in proteins and glycosidic bonds in carbohydrates.
What type of biochemical molecule is an enzyme?
An enzyme is a type of protein that acts as a biological catalyst, speeding up chemical reactions in living organisms.
How does the structure of an enzyme molecule affect its function in biological processes?
The structure of an enzyme molecule is crucial for its function in biological processes. Enzymes have specific shapes that allow them to bind to specific molecules, called substrates, and facilitate chemical reactions. This specificity is due to the precise arrangement of amino acids in the enzyme's active site. Changes in the enzyme's structure can affect its ability to bind to substrates and catalyze reactions, ultimately impacting the efficiency of biological processes.
What are free radical reactions?

These reactions can lead to chain reactions where a radical quickly reacts with another molecule to form a new radical. Free radicals are involved in various biological processes and environmental reactions.
What are the properties and functions of the hoh molecule in chemical reactions?
The H2O molecule, also known as water, has unique properties that make it essential for chemical reactions. It is a polar molecule, meaning it has a positive and negative end, allowing it to dissolve many substances. Water also has a high specific heat capacity, which helps regulate temperature changes in reactions. Additionally, water can act as a solvent, participate in acid-base reactions, and facilitate biological processes.
What characteristics of glycogen make it a good carbohydrate storage molecule?
- large insoluble molecule - wont affect water potential - relatively compact - wont be used up in reactions as its insoluble
What determines the presence of a chiral center in a molecule and how does it impact the molecule's properties and reactivity?
A chiral center in a molecule is determined by having four different groups attached to a central carbon atom. This asymmetry gives the molecule handedness, making it optically active. Chirality affects the molecule's properties and reactivity by influencing its interactions with other chiral molecules, enzymes, and biological systems. This can lead to differences in biological activity, drug effectiveness, and chemical reactions.
What is a molecule such as a neurotransmitter or a hormone that binds to a receptor called?
A molecule such as a neurotransmitter or hormone that binds to a receptor is called a ligand. This binding triggers a biological response in the target cell, influencing its function.
What type of organic molecule are enzymes?
the type of organic molecule an enzyme is would be a protien
Is ethanol a biological molecule?
Yes, it is.
