In a certain signal transduction pathway, the binding of an extracellular molecule to a cell-surface protein results in a rapid increase in the concentration of cyclic AMP inside the cell. The cyclic AMP binds to and activates cytosolic enzymes that then activate other enzymes in the cell. Which of the following statements best describes the role of cyclic AMP in this pathway?
The role of cyclic AMP is that it acts as a second messenger that helps relay and amplify the signal within the cell.
The process by which a chemical or physical signal is transmitted through a cell as a series of molecular events, most commonly protein phosphorylation catalyzed by protein kinases, which ultimately results in a cellular response is known as signal transduction. Proteins that detect stimuli are commonly referred to as receptors, though the term sensor is used in some cases. A biochemical cascade is a chain of biochemical events triggered by ligand binding (or signal sensing) in a receptor.
When signaling pathways interact, they form networks that allow cellular responses to be coordinated, frequently through combinatorial signaling events. Such responses at the molecular level include changes in gene transcription or translation, as well as post-translational and conformational changes in proteins, as well as changes in their location. These molecular events are the fundamental mechanisms that govern cell growth, proliferation, metabolism, and a variety of other processes. Signal transduction pathways regulate cell communication in a variety of ways in multicellular organisms.

HELP!!!!!!!! When oxygenated blood leaves the heart through the aorta, where does it travel to next?
A. to the body
B. to the lungs
C. to the heart
Answer: b- to the lungs
Explanation:
Answer:
When oxygenated blood leaves the heart through the aorta, it travels to the body. The aorta is the largest artery in the human body, and it carries oxygenated blood from the left ventricle of the heart to the rest of the body. The aorta branches off into smaller arteries, which distribute the oxygenated blood to the various organs and tissues of the body. This allows the cells of the body to use the oxygen in the blood to produce energy and perform essential functions.
In contrast, deoxygenated blood returns to the heart through the veins, and is then pumped to the lungs where it is oxygenated. The oxygenated blood then returns to the heart through the pulmonary artery and is pumped out to the body through the aorta. This is known as the cardiovascular system, and it is essential for maintaining the oxygen supply to the cells of the body.

Select which modifications you would make in cancer cells that are over expressing oncogenes. Check all that apply.
Modifications you would make in cancer cells that are over expressing oncogenes are Increase histone methylation while decreasing histone acetylation and phosphorylation.
It is generally known that both histone deacetylation and DNA methylation suppress gene transcription. In contrast, when histones are deacetylated by HDAC, their electrostatic contacts with DNA become stronger, resulting in relaxed chromatin that upregulates transcription. A more open conformation of chromatin is produced as a result of histone phosphorylation, which gives the histone a negative charge. As a result, it is linked to gene expression and is engaged in chromatin remodeling and DNA damage repair.
Methyltransferases and demethylases, respectively, catalyze the site-specific methylation and demethylation of histone residues.
