![]() So you don’t want to pick the activation choices, leaving us here with A and C. In response, you slow your Krebs cycle and all that mechanics down. The cell is in a really high energy state, which means you don’t need to make any more. (B) Activation of phosphofructokinase 1. ![]() Question 47: ATP/ADP RatioĪ cell in which an elevated ATP/ADP ratio exists is most likely to demonstrate which allosteric effect resulting for this elevation? So you have to go to the periodic table and see what’s element number 8 and you would see that it’s Oxygen. Fluorine which had 9 protons went down to only 8 protons. If shot off a positive charge, it means that one of it is positive, so the proton became a neutron. So if Fluorine starts with a mass of 18, shooting out a positron is not going to change the 18 at all because it didn’t give out any mass. Relative to a proton, you can treat beta decay as having a zero mass. So beta- is an electron while beta+ is a positively charged electron. It’s a position which is a fancy name for a positively charged electron. It doesn’t give you much except for the atomic number and then the element itself.įirst, you need to know the weight of a beta+ particle. The test would give you a periodic table where you click on the button in the corner of the screen. What does 18F become after a beta+ decay? In fact, in the Next Step Full Length analysis, about 65% get this question right while the other 35% all pick the aorta. If you’re not reading this question very carefully, you might pick (A) Aorta. So it’s in the capillaries that the blood flows the slowest that it almost comes to a standstill so that your oxygen and carbon dioxide can get exchanged. The blood in the aorta and the arterioles is just rushing along because of all that pressure from the heart. The question also says lowest fluid velocity. There are tens of thousands of capillaries for every arteriole, much less for the aorta and vena cava in the body. Within the body, which of the following blood vessels is expected to have the greatest total cross-sectional area and the lowest fluid velocity? Chylomicrons are the little clumpy bits that are used to transport fatty acids throughout the blood. So a glycerol backbone plus three fatty acids make up a full classic E-shaped triacylglycerol or just just fat molecule. Glycerol is the three-carbon backbone and fatty acids are the little tails that get tagged onto the glycerol.
