There are choices for this question namely:
Ativan 1 mg orally
<span>Nitroglycerin SL </span>
<span>Serum electrolytes </span>
<span>Chest x-ray
</span>
The correct answer is "Nitroglycerin SL". The SL means sublingually. The physician will still order Nitroglycerin to be taken sublingually whenever there is chest pain. The patient's medication may have been expired being stored for 12 months now. Ativan or Lorazepam will not be given as this is a sedative and there is no indication for sedatives.
Serum electrolytes and chest xray will not be requested as these diagnostic examinations are not usually done in patients with stable angina.
Answer:
OH, H2O2 and O−2
Explanation:
Reactive oxygen species (ROS) can be defined as highly reactive chemical compounds formed from molecular oxygen (O2). ROS are generated as a normal product of cellular metabolism, and also as a response to different environmental/internal cellular stimuli (e.g., cytokines, xenobiotics, pathogenic invasion). For example, hydroxyl radicals (·OH) are a type of ROS generated in the mitochondria which are capable of inducing oxidative stress in different cells and also trigger chronic inflammation. Moreover, hydrogen peroxide (H2O2) molecules represent another type of ROS which are produced during the stereoselective deamination of amino acids, i.e., the building blocks of proteins. These molecules (H2O2) exhibit toxic effects on the cell (e.g., DNA damage). Finally, singlet oxygen (1O2) is an excited state of molecular oxygen (O2) that is generated during photosynthesis in the photosystem II (PSII) of chloroplasts.
Mitochondria is the part responsible for making the ATP for the cells.
