Substances foreign to the host that can stimulate an immune response are known as: Cytokines Antigens MHC proteins Antibodies
The substances foreign to the host that can stimulate an immune response are known as antigens. Antigens are molecules or particles that the immune system recognizes as non-self and triggers an immune response to eliminate them.
These antigens can come from viruses, bacteria, fungi, parasites, or even from transplanted tissues and organs. When antigens enter the body, they interact with specialized cells of the immune system, called antigen-presenting cells, which then present them to other immune cells, such as T cells and B cells. These cells then produce specific molecules, such as antibodies and cytokines, that target and destroy the antigens. MHC proteins also play a critical role in presenting antigens to immune cells.
In contrast, Cytokines are signaling molecules that regulate immune responses, MHC proteins present antigens to T cells, and Antibodies are proteins produced by B cells to recognize and neutralize antigens.

A metabolically stressed epithelial cell expresses the protein MIC-A on its surface, and then interacts with a natural killer (NK) cell. What is the outcome of this interaction
When a metabolically stressed epithelial cell expresses the protein MIC-A on its surface and interacts with a natural killer (NK) cell, the outcome of this interaction can be the killing of the stressed cell by the NK cell.
MIC-A is a protein that is normally only found on the surface of cells that have been infected with a virus or have undergone a transformation, but can also be expressed on cells that are metabolically stressed or damaged.
NK cells are a type of white blood cell that plays a critical role in the innate immune response.
They are able to recognize and kill cells that have become abnormal, such as cells infected with a virus or that have undergone malignant transformation.
When an NK cell encounters a cell that has expressed MIC-A, it recognizes this as a signal of cellular stress or damage and can trigger the release of cytotoxic granules that contain perforin and granzyme.
These granules enter the stressed cell and induce apoptosis, or programmed cell death, leading to the elimination of the damaged or infected cell.
Overall, the interaction between a metabolically stressed epithelial cell expressing MIC-A and an NK cell can result in the elimination of the stressed cell, helping to prevent the spread of infection or the development of cancer.

Taxol, a plant alkaloid originally found in yew trees, is an anticancer drug. How does Taxol prevent cell division
Taxol is an anticancer drug that prevents cell division by targeting the microtubules, which are protein structures that play a crucial role in cell division.
During cell division, microtubules help to separate the chromosomes and distribute them evenly to each daughter cell. Taxol binds to the microtubules and stabilizes them, which prevents them from breaking down and causes the cell division process to halt. This results in the inhibition of cancer cell growth and proliferation.
Taxol works by binding to a specific site on the microtubules known as the beta-tubulin subunit. By stabilizing the microtubules, Taxol prevents the formation of the mitotic spindle, which is required for the proper segregation of chromosomes during cell division. This results in the arrest of the cell cycle and ultimately leads to the death of the cancer cells.
Furthermore, Taxol also induces apoptosis, or programmed cell death, in cancer cells. This is achieved by activating specific enzymes and pathways that lead to the fragmentation and degradation of cancer cells.
In summary, Taxol is an effective anticancer drug that prevents cell division by stabilizing microtubules and inhibiting the formation of the mitotic spindle. Its ability to induce apoptosis further enhances its therapeutic potential in the treatment of cancer.

Calculate the ATP yield from oxidation of stearic acid, taking into account the energy needed to activate the fatty acid and transport it into mitochondria.
The ATP yield from the oxidation of stearic acid, taking into account the energy needed to activate the fatty acid and transport it into mitochondria is 32.5 ATP.
Stearic acid is an 18-carbon saturated fatty acid, which undergoes activation by converting into stearoyl-CoA, costing 2 ATP molecules. Next, it enters the mitochondria via the carnitine shuttle, which does not require additional ATP. Once in the mitochondria, the stearoyl-CoA undergoes β-oxidation, which involves a series of reactions that cleave the fatty acid into 2-carbon acetyl-CoA units. Since stearic acid has 18 carbons, it produces 9 acetyl-CoA molecules.
Each round of β-oxidation yields 1 FADH² and 1 NADH, except for the final round, which yields an additional NADH. Therefore, stearic acid produces 8 FADH² and 9 NADH molecules through β-oxidation. These molecules enter the electron transport chain, generating ATP via oxidative phosphorylation. NADH generates 2.5 ATP, while FADH2 generates 1.5 ATP.
Thus, the total ATP yield is (9 NADH × 2.5) + (8 FADH2 × 1.5) = 22.5 + 12 = 34.5 ATP.
Subtracting the 2 ATP used for activation, the net ATP yield from stearic acid oxidation is 32.5 ATP.

The reserve and residual volumes of air that remain in the lungs occupy about 2015 mL and a single respiratory cycle for an average human takes about 4 seconds. Find a model for the total volume of air V(t) in the lungs as a function of time.
The change in volume during one respiratory cycle is: ΔV = 508 mL
Let V(t) be the total volume of air in the lungs at time t, measured in milliliters (mL).
The reserve and residual volumes of air that remain in the lungs occupy about 2015 mL, which is the volume of air in the lungs at the end of a respiratory cycle. Therefore, we can model the total volume of air in the lungs as a function of time using a sinusoidal function with a horizontal shift of 4 seconds and an amplitude of 1007.5 mL (half the difference between the maximum and minimum volumes):
V(t) = 1007.5 sin(π/2 * (t-4)) + 2015
Note that we use a horizontal shift of 4 seconds since a single respiratory cycle for an average human takes about 4 seconds. The sinusoidal function models the change in volume during a single respiratory cycle, and the constant term accounts for the residual volume of air that remains in the lungs at the end of a cycle.
