Answer:
The statements that correctly describes pyruvate dehydrogenase includes:
- Several copies each of E 1 and E 3 surround E 2.
-A regulatory kinase and phosphatase are part of the mammalian PDH complex.
-E 2 contains three domains.
Explanation:
Pyruvate dehydrogenase is a hydrolase key enzyme in glucose metabolism which converts pyruvate to acetyl- ChoA. It also forms a complex that catalyzes an irreversible reaction that is the entry point of pyruvate into the TCA cycle. Pyruvate dehydrogenase complex contains E1, E2 and E3 enzymes that transform pyruvate, NAD+, coenzyme A into acetyl-CoA, CO2, and NADH. Also, A regulatory kinase and phosphatase are part of the mammalian PDH complex and E 2 contains three domains.
4 mol / 205g H2O = 4/.205 = 19.5 mol/kg boiling point = 100 + 19.5 • 0.51 = 109 ºC
Answer:
Today, the vast majority of us multitask while using our smartphones. We play games, email, surf social media, text, and use apps and other functions while watching television, eating, doing work, or while "engaged" in a conversation with another person. Multitasking has become such a regular part of our lives that most of us believe we do it well—and few imagine it could actually be dangerous.
Explanation:
1. Multitasking is associated with harm to our brains.
2. Multitasking can lead to memory problems.
3. Multitasking can lead to increased distractibility.
4. Multitasking can make us walk into traffic.
5. Multitasking hurts your grades and the grades of those around you.
6. Multitasking can lead to falling and breaking bones.
7. Multitasking can harm your relationship.
8. Multitasking increases chronic stress.
9. Multitasking increases depression and social anxiety.
10. Multitasking makes you less productive and less efficient.

Explanation:
What happens during gas exchange in the alveoli?
These are called alveoli. They inflate when a person inhales and deflate when a person exhales. During gas exchange oxygen moves from the lungs to the bloodstream. At the same time carbon dioxide passes from the blood to the lungs.
What is the role of alveoli in gas exchange?
The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out. Oxygen breathed in from the air passes through the alveoli and into the blood and travels to the tissues throughout the body.
