Give typed full explanation of both questions otherwise leave it 1) You generate action potentials in a neuron bathed in solution in a petri dish by applying a threshold level depolarizing stimulus near its axon hillock. If the solution surrounding the neuron contained 5mM K+, 150 mM Na+, and 0 mM Ca2+ which of the following would you expect? a. the neuron would not release neurotransmitter from the axon terminal b. the neurons action potentials would have an unusually long duration c. the neuron would have a resting membrane potential of zero d. the neuron would not be able to propagate action potentials down the entire length of the axon 2) If blood pressure decreases, which of the following would allow glomerular filtration rate to remain unchanged? a. dilation of both the efferent and afferent arterioles b. dilation of efferent arterioles and constriction of afferent arterioles c. constriction of efferent arterioles and dilation of afferent arterioles d. constriction of both the efferent and afferent arterioles
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.
