A drug binds to sodium voltage-gated channels and prevents them from opening. Which of the following statements is TRUE in this scenario? Assume the cell is starting at resting membrane potential (RMP) of -70mV. (although ions may try to cross the membrane to counteract this changing gradient if possible, what is the effect of this drug before this might happen) The neuron cannot undergo a depolarizing graded potential. K+ will be unable to diffuse out of the neuron The neuron cannot undergo a hyperpolarizing graded potential The neuron will be unable to fully depolarize to peak, even if threshold is reached
Enzyme kinetics
In biochemistry, enzymes are proteins that act as biological catalysts. Catalysis is the addition of a catalyst to a chemical reaction to speed up the pace of the reaction. Catalysis can be categorized as either homogeneous or heterogeneous, depending on whether the catalysts are distributed in the same phase as that of the reactants. Enzymes are an essential part of the cell because, without them, many organic processes would slow down and thus will affect the processes that are important for cell survival and sustenance.
Regulation of Enzymes
A substance that acts as a catalyst to regulate the reaction rate in the living organism's metabolic pathways without itself getting altered is an enzyme. Most of the biological reactions and metabolic pathways in the living systems are carried out by enzymes. They are specific for their works and work in particular conditions. It maintains the best possible rate of reaction in the most stable state. The enzymes have distinct properties as they can proceed with the reaction in any direction, their particular binding sites, pH specificity, temperature specificity required in very few amounts.
