Answer: D: Enzymes increased the rate of the chemical reactions carried out during metabolism.

Explanation:

Energy production in the cell requires the participation of many enzymes in a process called energy metabolism. Many of these reactions occur very slowly in the absence of a catalyst (a substance that accelerates the speed of chemical reactions). To solve this problem, cells have developed a way to accelerate the speed of reactions. In this context arise the enzymes that are the biological catalysts. Most enzymes are globular proteins. They have specificity (preference) both for their substrates (the molecule that will undergo the chemical reaction) and for the type of reaction on the substrate.

Which of the following best describes REM sleep?
Stells [14]
<h2>Answer:</h2>

Sleep in which the brain becomes more active but muscle activity is blocked.

<h3>Explanation:</h3>

The brain cycles through five distinct phases during sleep: stages 1, 2, 3, 4, and rapid eye movement (REM) sleep. REM sleep makes up about 25% of your sleep cycle and first occurs about 70 to 90 minutes after you fall asleep. Because your sleep cycle repeats, you enter REM sleep several times during the night.

  • During REM sleep, your brain and body are energized and dreaming occurs.
  • REM is thought to be involved in the process of storing memories, learning, and balancing your mood.
  • REM sleep begins in response to signals sent to and from different regions of the brain. Signals are sent to the brain's cerebral cortex, which is responsible for learning, thinking, and organizing information.

A client undergoes cerebral angiography for evaluation of a subarachnoid hemorrhage. which findings indicate spasm or occlusion
DerKrebs [107]

Hemiplegia, seizures, and decreased level of consciousness are the  findings which indicate spasm or occlusion of a cerebral vessel by a clot.

The spasm or occlusion of a cerebral vessel by a clot leads to symptoms similar to those of a stroke.

The subarachnoid hemorrhage may occur as a complication type of a stroke called a hemorrhagic stroke, or bleeding inside the brain.

The hemiplegia, seizures, decreased level of consciousness, aphasia, hemiparesis, and increased focal symptoms.

Therefore, nausea, vomiting, and profuse sweating suggest a delayed reaction to the contrast medium used in cerebral angiography. The difficulty in breathing or swallowing may signal a hematoma in the neck. Tachycardia, tachypnea, and hypotension suggest internal hemorrhage.
