A negative ΔG value indicates that the reaction is spontaneous and can occur without external energy input.

The splitting pattern, or multiplicity, indicates the number of neighboring protons that influence the magnetic environment of the observed nucleus.

FTIR stands for Fourier Transform Infrared spectroscopy, a technique used to obtain an infrared spectrum of absorption or emission of a solid, liquid, or gas.

HPLC stands for High Performance Liquid Chromatography, a technique used for separating, identifying, and quantifying components in a mixture.

Km is the substrate concentration at which the reaction rate is half of Vmax, indicating the enzyme's affinity for the substrate.

NMR stands for Nuclear Magnetic Resonance, a technique used to observe the magnetic properties of atomic nuclei.

The chemical shift provides information about the electronic environment surrounding the nuclei, which helps in identifying functional groups.

Bioavailability refers to the proportion of a drug that enters the circulation when introduced into the body and is available for therapeutic effect.

Incidence measures the number of new cases that develop in a given time period.

Prevalence refers to the total number of cases of a disease present in a population at a given time.

A competitive inhibitor increases the Km of the enzyme, indicating a higher substrate concentration is needed to reach half-maximal velocity.

Aldosterone increases sodium reabsorption in the kidneys, which also leads to increased water retention and higher blood pressure.

An allosteric activator increases enzyme activity by enhancing the enzyme's affinity for its substrate.

Citric acid imparts a sour flavor to food, enhancing its taste profile.

Increasing substrate concentration generally increases enzyme activity until the enzyme becomes saturated and reaches its maximum rate.

Increasing temperature generally increases enzyme activity up to an optimal point, after which activity declines due to denaturation.

Increasing temperature typically decreases protein stability due to denaturation.

Increasing the diameter of a blood vessel decreases resistance, thereby increasing blood flow according to Poiseuille's law.

Temperature can significantly affect immobilized enzyme activity, potentially leading to denaturation at high temperatures.

Reverse transcriptase is crucial for the replication of Retroviridae viruses, converting RNA into DNA.

Cloning vectors usually contain antibiotic resistance genes to allow for the selection of successfully transformed cells.

During the G0 phase, cells exit the cell cycle and enter a quiescent state, where they are metabolically active but not dividing.

When an enzyme is denatured, it loses its functional three-dimensional shape, rendering it inactive.

At high temperatures, enzymes can denature, losing their functional shape and activity.

When lactose is present, it binds to the lac repressor, causing a conformational change that inactivates the repressor and allows transcription of the lac operon.

High-grade tumors typically exhibit increased mitotic activity, presence of necrosis, and poorly differentiated cells, making 'All of the above' the correct answer.

Glucagon is secreted by the pancreas and raises blood glucose levels by promoting glycogen breakdown in the liver.

Bacteriophages are viruses that specifically infect and replicate within bacteria.

A cofactor is a non-protein molecule that assists enzymes in catalyzing reactions, often by stabilizing the enzyme-substrate complex.

Aminoglycosides are known to cause ototoxicity, which can lead to hearing loss.
