Answer:
high clean-energy startup costs
Explanation:
Protecting the environment means improving its sustainability and reducing pollution to the barest minimal. This utterly means terminating every activity that contributes to pollution in the environment, including the source of energy. The most widely used source of energy is the non-renewable source e.g. coal, fuel, etc.
These source of energy, however, release pollutants in form of greenhouse gases, into the environment. One way to eliminate the use of non-renewable source of energy is to adopt the use of renewable sources e.g. solar energy, wind etc. However, one major setback to doing this is the high production cost involved.
Although these sources of energy (renewable) are referred to as green or clean, but they have really expensive startup costs and are unaffordable most times.
Answer:
Electron transfer to from cytochrome c to molecular Oxygen in the process of oxidative phosphorylation
Explanation:
Cytochrome c is a protein which is involved in the electron transport chain for the production of ATP molecules during then process of respiration. It a soluble protein found in the intermembrane space of the mitochondria. It receives electrons from ubiquinone at Complex III of the electron transport chain and transfers this electron to molecular oxygen through its interaction with complex IV or cytochrome c oxidase, reducing molecular oxygen to water.
If the interaction of cytochrome c with cytochrome c oxidase is inhibited, the process of elctron transfer to oxygen will be inhibited and, so ATP synthesis will cease.
Ultimately, respiration will be inhibited resulting in death of the organism. For example, cyanide inhibits cytochrome c oxidase resulting in death of the organism poisoned with cyanide.
The client with chronic hypertension with a current blood pressure reading of 182/98 mmHg should be managed first. According to the AHA guidelines for hypertension, this is considered as a hypertensive urgency and should be managed first by having the patient lie down comfortably and reassessing the blood pressure again. If there is no improvement, the patient should be referred to a physician and a rapid blood pressure lowering drug should be given (i.e. Clonidine 75 mcg tablet sublingually up to 3 doses every 15 minutes). The patient with right-sided heart failure with edema can be treated non-urgently or as out-patient with diuretics. The patient asking for a refill can be entertained last.
