The trаnspоrt оf а substаnce acrоss a plasma membrane of a specific organelle requires energy. The rate at which the transport takes place also depends on temperature. A scientist isolated the specific organelle and then used the following treatments to determine the conditions that will result in the maximal transport. All treatments contained the extracted organelle and were maintained at 25°C. The data from this experiment indicate that maximal rate of transport of protein X at 25°C occurs at an ATP concentration of 1.0μm/mL. The figure shows the following four ATP concentrations used in the experiment: 0.2 micromoles per milliliter, 1.0 micromole per milliliter, 2.0 micromoles per milliliter, and 5.0 micromoles per milliliter. Figure 1. The four ATP concentrations used in the experiment Which procedure should be done next to gather data needed to meet the scientist’s objective?
Insulin, а hоrmоne secreted by pаncreаtic cells, stimulates glucоse uptake in skeletal muscle cells by mobilizing glucose transporter proteins (GLUT4) to the plasma membrane. As depicted in Figure 1, binding of insulin to the insulin receptor triggers an intracellular signaling cascade in which certain molecules activate other molecules in a relay of the hormone signal to cell targets. One outcome of the signaling cascade is mobilization of GLUT4 from vesicle storage sites in the cytoplasm to sites at the cell surface, where GLUT4 allows glucose to enter the cell. The figure shows a large oval shape representing a cell and is labeled, Figure One. Insulin signaling in muscle cells. The figure shows the binding of Insulin, which is outside the cell, to the insulin receptor, which is embedded in the plasma membrane. This triggers an intracellular signaling cascade in which the insulin receptor activates I R S-1, which activates P I 3-Kinase, which activates P D K, which activates A k t, which activates Glut 4 Vesicles, which fuse with the Plasma Membrane. Glut 4 becomes embedded in the plasma membrane, and glucose molecules move from outside the cell to inside the cell. Figure 1. Insulin signaling in muscle cells. In type 2 diabetes, the cellular response to insulin is disrupted, and individuals with type 2 diabetes cannot properly regulate their blood glucose levels. In an investigation of the insulin signaling pathway, samples of skeletal muscle were isolated from individuals who have type 2 diabetes and from individuals who do not. The results of several experiments that were performed on the muscle samples are shown in Figure 2, Figure 3, and Figure 4. The figure shows 3 graphs. The first graph is labeled Figure 2. Insulin-stimulated glucose uptake. The horizontal axis is labeled Insulin, in nanomolars. The vertical axis is labeled Glucose Transport, in nanomoles per milligram, hour. Five numbers appear on the horizontal axis and are, from left to right, zero, zero point six, one point two, 2 point four, and 60. A break in the axis occurs between 2 point four and 60. Eleven numbers appear on the vertical axis and are, from bottom to top, zero through 10, in increments of one. A solid line and a dashed line, each with data points, appear on the graph. The dashed line is labeled Control and connects 5 data points. The leftmost and rightmost data points are the start and end of the line, and the approximate coordinates of the data points are as follows: Point One: zero comma 2. Point 2: zero point six comma 6. Point 3: one point two comma 9. Point 4: two point four comma 8 point five. Point 5: 60 comma 9. The solid line is labeled Type 2 diabetic and connects 5 data points. The leftmost and rightmost data points are the start and end of the line, and the approximate coordinates of the data points are as follows: Point One: zero comma 2. Point 2: zero point 6 comma 2 point one. Point 3: one point two comma zero point nine. Point 4: two point four comma 5. Point 5: 60 comma 6. The second graph is labeled Figure 3. Insulin receptor activation. The horizontal axis is labeled Insulin, in nanomolars. The vertical axis is labeled Relative Activity. Three numbers appear on the horizontal axis and are, from left to right, zero, 2 point four, and 60. An unnumbered tick mark appears to the right of 60, and a break in the axis occurs between 2 point four and 60. A solid and a dashed line with data points appear on the graph. The dashed line is labeled Control and connects 3 data points. The line begins on the vertical axis, slightly above the intersection of the axes and at a point of zero nanomolars. The line moves gradually up and to the right, to a point approximately one fourth above the horizontal axis and at 2 point 4 nanomolars, then moves steeply up and to the right, and ends at a point near the top of the graph at 60 nanomolars. The solid line is labeled Type 2 diabetic and connects 3 data points. The line begins on the vertical axis, just above the first Control point. The line moves gradually up and to the right, to a point just below the second Control Point and at 2 point 4 nanomalors, then moves steeply up and to the right, and ends at a point slightly above the third Control point and at 60 nanometers. The third graph is labeled Figure 4. I R S-one activation. The horizontal axis is labeled Insulin, in nanomolars. The vertical axis is labeled Relative Activity. Five numbers appear on the horizontal axis and are, from left to right, zero, zero point six, one point two, 2 point four, and 60. A break in the axis occurs between 2 point four and 60. A solid line and a dashed line with data points appear on the graph. The dashed line is labeled Control and connects 5 data points. The line begins at the intersection of the axes, and moves gradually up and to the right, to a point slightly above the horizontal axis and at zero point six nanomolars, then moves gradually down and to the right, to a point below the first point, above the horizontal axis, and at one point 2 nanomolars, then moves gradually up and to the right, to a point approximately one third above the horizontal axis, slightly above the first point, and at 2 point 4 nanomolars, then moves steeply up and to the right, and ends at a point near the top of the graph and at 60 nanomolars. The solid line is labeled Type 2 diabetic and connects 5 data points. The line begins at the intersection of the axes, and moves gradually up and to the right, to a point slightly below the first Control point and at zero point six nanomolars, continues on to a point slightly above the second Control point and at one point two nanomolars, then moves to the right, approximately parallel to the horizontal axis, and to a point below the third Control point, above the horizontal axis, and at 2 point 4 nanomolars, then moves gradually up and to the right, and ends approximately one third above the horizontal axis, at 60 nanomolars. Based on the experimental results, which of the following describes the most likely defect in muscle cells of patients with type 2 diabetes?
The figure presents twо prоcesses. The first prоcess is fertilizаtion. A sperm fusing with аn egg is shown. The second process is trаnsduction. A five step process is shown. Step 1. Virus attaches to cell surface and inserts viral DNA into cell. Step 2. The cell’s circular DNA is broken into many pieces. Step 3. new viral particles are formed in the cell that include DNA from the host cell. Step 4. One of the new viral particles infects another cell. Step 5. The DNA from the virus is inserted into the circular chromosome of the shot cell. Which of the following correctly compares the two processes shown above?
