- Explain the following term, be sure to include energy requirements for each process and a biological example of each process: Simple diffusionExplain the following term, be sure to include energy requirements for each process and a biological example of each process: active transportClassify the following into either activation processes or inhibitions processes. Process Phosphorylation of a transport protein (i.e. pump) The binding of a substrate molecule at the active site of an enzyme The binding of a molecule at the active site of an enzyme, but in place of the substrate The allosteric binding of ATP to the phosphofructokinase (an enzyme part of glycolysis)
- Please handraw this graph with all the necessary detailed information: Imagine that I text enzyme rate for four different temperatures: 10 degrees celsius, 20 degrees celsisus, 30 degree celsius, and 40 degree celsius, in separate tubes. The enzyme appears to work faster as temperature increases, but completely ceases activity at 40 degrees celcius. Sketch a graph to show this outcome, but here you will graph product formation (nmoles/mL) vs. time (minutes). The graph should be 4 lines and HANDDRAWN. Include a legend if necessary. You do not need precise quantitivate values, but most show the correct trends on the graph.Describe the role that compartmentation plays in the regulation of metabolic pathways. Provide several examples.Select the correct statement regarding electrochemical gradients. Thermodynamically, electrochemical gradients will maintain their relative concentrations across both sides of the membrane. The cytoplasmic side of the cell membrane has a net positive charge relative to the extracellular side. Ions can freely pass through the cell membrane. Electrochemical gradients are sources of potential energy due to the differences in concentrationsand charge across both sides of the cell membrane. Select the correct statement(s) about transfer RNAs. Codon recognition occurs through specific base-pairing by the anticodon arm. Amino acids are linked to the T-loop. They are transcribed by RNA Polymerase III. There is strict matching requirements at the third position, else the tRNA cannot interact with the codon.
- For each of the statements below about the dUTPase enzyme, mark whether it is true or false. If it is false, change the language to make the statement true. _______If the dUTPase enzyme is the rate determining step in a larger metabolic pathway, the reaction likely lies near to equilibrium and is irreversible. _______For the dUTPase reaction, it is not likely that DG’ = DG°’ _______ dUTPase has a higher affinity for its substrate than for its product, but both of these are higher than the affinity for the transition state _______Kinetic analysis of dUTPase using Michaelis-Menten methods assumes that the formation of the E*S complex has a large negative value for DGIndicate whether each of the following statements about enzyme terminology is TRUE or FALSE. All conjugated enzymes contain a cofactor. An apoenzyme has both a protein and nonprotein part. Metal ions cannot be present in a cofactor. An apoenzyme is present in all holoenzymes. Simple enzymes cannot contain cofactors. A holoenzyme has both a protein and nonprotein part. Metal atoms are present in all conjugated proteins. A cofactor is present in some, but not all, conjugated enzymes.The capacity to do work best defines: a metabolic pathway. entropy. kinetic or potential energy. a chemical equilibrium. thermodynamics.

Substrate-limited:Two substrates (A and B) are used to produce a certain biological product in an enzyme- catalyzed reaction. It is found that both substrates must bind to the enzyme, first Substrate A, then Substrate B before the product is produced. What kind of kinetic mechanism is described?
