NU 545 Unit 1 Study Guide Latest With Correct Answers. What is metabolic absorption? - ANSWER The uptake and use of nutrients and other substances from the cells surrounds What uses oxygen to remove hydrogen atoms in an oxidative reaction? - ANSWER Peroxisomes contain enzymes to use o2 to remove H atoms. This produces hydrogen peroixide. During cell injury what is released that is capable of cellular autodigestion? - ANSWER Lysosomes aid in cellular digestion, seen as "trash cans and re...

WGU pathophysiology D236 study guide Certification Exam answers verified What is Starling's Law of Capillary forces? How does this explain why a nutritionally deficient child would have edema? - CORRECT ANSWER-Starling's Law describes how fluids move across the capillary membrane. There are two major opposing forces that act to balance each other, hydrostatic pressure (pushing water out of the capillaries) and osmotic pressure (including oncontic pressure, which pushes fluid into th...

Higher in low socioeconomic in western world 2.) Higher in minority...

What is the difference between the net number of ATP generated by glycolysis from glucose produced by the glycogen phosphorylase enzyme reaction as compared to glucose obtained from the diet? correct answers One less net ATP is generated in glycolysis from dietary glucose as compared to glucose from glycogen. Part 1: Glycogen metabolism is regulated by both allosteric control and covalent modification. Circle the best underlined words describing glycogen regulation and record the number. corr...

What is glucose regulation? The process of maintaining optimal blood glucose levels What is the ultimate end goal of glucose metabolism? Cellular use of glucose for energy (ATP) What is glycogen? Major form of stored glucose; can be found in the liver or muscle tissue What is glycogenolysis? Converting glycogen to glucose What are the counter-regulatory hormones? Hormones that aid the process of glycogenolysis including: glucagon, epinephrine, growth hormone, and...

Angioedema -Correct Answer-A puffiness of face, lips, and neck due to swelling underneath the skin; common in allergic reactions Aura -Correct Answer-the state of mind just before the onset of a seizure; strange feeling, some may experience visions Diabetes type-I -Correct Answer-Juvenile diabetes requires daily insulin injection Diabetes type-II -Correct Answer-Adult onset diabetes, can be controlled by diet, exercise, and weight loss Dysarthria -Correct Answer-Slurred speech Exp...
