QUESTION 55 ARDS can lead to acidosis. The decreased pH increases the rate of the body's...
QUESTION 44 Which of the following relate to acute respiratory distress syndrome (ARDS) during SIRS? Due to lack of oxygenation of the blood, body cells switch to fermentation in order to obtain energy. Fermentation can lead to lactic acidosis of the blood, Acidosis can decrease the rate of the body's cellular enzyme activity. A and B A, B and
Question 44 Hyperventilation can lead to Metabolic acidosis Metabolic alkalosis Respiratory acidosis Respiratory alkalosis
Activity 3: Renal Responses to Respiratory Acidosis and Respiratory Alkalosis pCO2 Blood pH H in urine HCO3 in urine 40 30 60 Question: 3. With renal compensation of respiratory acidosis, the pH of the urine (increases or decreases). Activity 4: Respiratory Responses to Metabolic Acidosis and Metabolic Alkalosis Questions: 4. What happened to the blood pH when the metabolic rate went from 40 to 80 kcal/hr? 5. What happened to the breaths per minute when the metabolic rate went from...
The rate of an enzyme-catalyzed reaction initially increases with an increase in the substrate concentration, but eventually reaches a maximum value, even though the concentration of substrate continues to increase. Which of the following best explains why? O As substrate concentration increases, the substrates preferentially bind with each other instead of the active site of the enzyme, and no additional catalysis occurs. As substrate concentration increases, the active sites of all the enzyme molecules become occupied with substrate molecules, and...
QUESTION 56 ARDS can be triggered by overproduction of inflammatory cytokines in response to PAMPs binding to PRRs during a severe systemic infection, True False
1 a) A sudden increase in lactic acid levels during exercise can lead to metabolic acidosis. Acidosis is commonly treated by administering NaHCO, intravenously. Using the bicarbonate-carbon dioxide buffer system, qualitatively explain the effect of this procedure on blood pH. [6 points) b) The phosphate buffer system is another buffer system in the blood. Phosphates are found in the blood in two forms: sodium dihydrogen phosphate (Na2H2PO4), which is a weak acid, and sodium monohydrogen phosphate (Na2HPO 2), which is...
Question 37 Which of the following increases oxygen unloading? decreased BPG e decreased pCO2 in the plasma All of these answers are correct. increased blood pH increased body temperature Question 38 What is a classic scenario, as described in class, where oxygen unloading would be increased? while eating food during exercise during tidal volume breathing while drinking water divas → XCIO D Question 39 Which of the following is FALSE regarding breathing? It requires skeletal muscles for normal, quiet exhalation....
Test Your Knowledge Question 2 Question 2 of 2 2. Identify each statement as true or false. A low pH may denature an enzyme As the concentration of a substrate in a solution increases, the enzymatic activity will always continue to increase Lactose is an enzyme that breaks down lactase :: pH is determined by (H') present in solution His :: Temperatures that are too high may denature an enzyme : Too many enzymes present in a solution may denature...
Question 41 2 pts Glycolysis produces the same amount of ATP during anaerobic fermentation that the Citric Acid Cycle does during aerobic cellular respiration. True False Question 42 2 pts Resonance energy transfer in the antenna complex of a photosystem involves a series of electron transfer (redox) reactions. True False Question 43 2 pts The energy found in carbohydrates, proteins, and lipids can be converted into ATP energy by aerobic cellular respiration True False Question 44 2 pts Alterations in...
