Frequently Asked Questions
What are the main components of nucleic acids?
Nucleic acids are primarily composed of nucleotide monomers, which consist of a phosphate group, a sugar (ribose in RNA and deoxyribose in DNA), and a nitrogenous base.
How do enzymes function as biological catalysts?
Enzymes speed up chemical reactions by lowering the activation energy required for the reaction to proceed, thereby increasing the rate of the reaction without being consumed in the process.
What is the significance of pH in biochemical reactions?
pH affects the ionization of functional groups in biomolecules, which can alter enzyme activity, substrate binding, and overall reaction rates, making it a critical factor in biochemical processes.
What role do lipids play in cellular membranes?
Lipids, especially phospholipids, form the basic structure of cellular membranes, creating a bilayer that is semi-permeable and essential for compartmentalization and membrane fluidity.
What is the central dogma of molecular biology?
The central dogma describes the flow of genetic information from DNA to RNA (transcription) and then from RNA to protein (translation), outlining the process of gene expression.
How do competitive and non-competitive inhibitors differ?
Competitive inhibitors bind to the active site of an enzyme, competing with the substrate, while non-competitive inhibitors bind to an allosteric site, changing the enzyme's shape and reducing its activity regardless of substrate presence.
What is glycolysis, and why is it important?
Glycolysis is the metabolic pathway that converts glucose into pyruvate, producing ATP and NADH in the process; it is crucial for cellular respiration and energy production in both aerobic and anaerobic conditions.
What are the differences between saturated and unsaturated fatty acids?
Saturated fatty acids have no double bonds between carbon atoms, leading to a straight structure, while unsaturated fatty acids contain one or more double bonds, causing kinks that affect their physical properties and fluidity.
What is the purpose of the Krebs cycle?
The Krebs cycle, also known as the citric acid cycle, is a series of enzymatic reactions that generate energy through the oxidation of acetyl-CoA, producing NADH, FADH2, and ATP, which are used in the electron transport chain.
How does the structure of proteins relate to their function?
The specific sequence of amino acids determines a protein's three-dimensional structure, which in turn dictates its function; changes in structure can lead to altered function or loss of activity.
