According to Ohm's Law, what is the mathematical relationship between voltage (V), current (I), and resistance (R) in an electrical circuit?
V = I * R.
DAILY DOUBLE π
In the citric acid cycle (Krebs cycle), which enzyme catalyzes the conversion of isocitrate to alpha-ketoglutarate?
Isocitrate dehydrogenase.
In a chemical reaction, if the reactants have lower potential energy than the products, what type of reaction is occurring?
Exothermic reaction
This type of nucleophilic substitution reaction is characterized by a two-step mechanism and often involves the formation of a carbocation intermediate.
SN1 Reaction
Name two mechanisms through which gene expression is regulated in prokaryotes, specifically focusing on post-transcriptional modifications.

In a double-slit experiment, what phenomenon occurs when light or electrons interfere and create alternating bright and dark fringes on a screen?
Answer: Interference.
What is the term for the phenomenon where an enzyme's activity is altered by the binding of a regulatory molecule at a site other than the active site?
Answer: Allosteric regulation.
Which principle states that no two electrons in an atom can share the same set of quantum numbers, specifically their spin?
