How many possible alleles are at a locus consisting of 3 base-pairs in a diploid? ugh, I am so confused... So, I guess a locus is just a spot for a gene, so the gene is also considered to consist of 3 bases. Gene: _ _ _ Each "_" could be either an A,T,C, or G. So there are 4 possibilities...

My understanding is that monosaccharides circulating in the bloodstream enter cells to undergo cellular respiration. Glucose requires insulin to enter cells, but fructose and galactose do not (insulin-independent)? Is the above statement correct? I was wondering, then, if untreated...

In order to break down body fat or muscle, do you first have to undergo glycogenolysis and then gluconeogenesis? I assume ketone bodies (made in the liver from fatty acids) are just used as a way to export acetyl CoA (derived from body fat, fat from food, muscle, or protein from food) to other...

Since most normal body cells do need insulin to take up glucose, do type 1 diabetics instead have to run off of ketone bodies when insulin is not present? *If this is the case, wouldn't weight loss in untreated type 1 diabetics actually make their blood sugar go even higher but also be...

So my understanding is that capillaries leak out their blood plasma containing sugar and other nutrients insulin (when sugar present)near body cells, and this is what comprises interstitial fluid. But what if no insulin is present (Type 1 diabetes) or insulin creates no response (Type 2...

I was saying that active transport does take place in the intestines, which you are confirming is correct? But I'm wondering how 1. glucose gets from interstitial fluid of villi into capillaries and 2. from capillaries to interstitial fluid between cells and 3. from interstitial fluid to cell...

I am trying to understand about glucose metabolism! I have been researching this stuff forever! X( Would you see if my explanations are right, and if not, tell my why? Thank you SO much! That would be a HUGE help! Is it true that uptake and release of gas/nutrients only occur in the...

I have been looking at this enzyme kinetics stuff forever and was trying to come up with a summary for things... #=_= Is this even right...? :/ |---------------|This segment I'm calling "Part 2" k1 k2 E + S ES E + P k-1 |---------------|This...

1. "Students were instructed to mix the benzaldehyde and acetone starting materials in their conical vials before adding the ethanolic sodium hydroxide solution. Why was this essential to the success of the reaction? What would have been the most likely product formed if the sodium hydroxide...

Oh, wow! My problem was not using the right formula! :P Formula for electric potential energy between charges: Uq,Q = (kqQ)/r Formula for electric potential between charges: Vq,Q = \frac{kq}{x} + \frac{kQ}{(x2)-x} Let me know if I have this right, please: If I have 2 charges (q at...

1. A system consists of the charges -q at (-d,0), +2q at (d,0), and +3q at (0,d). What is the total electric potential energy of the system. 2. I'm wondering, is it necessary to calculate each electric potential between charges from lower electron potential to higher electron potential...

(+) Particle~ proton \vec{F} = q\vec{E} Since everything is positive, the Force and \vec{E} point in the same direction? (-) Particle~ electron \vec{F} = -q\vec{E} \vec{E} and the force of the electron point in opposite directions. The electron goes from B to A to high...

Okay, so even though our electric field flows from top to bottom (+ to -) in the picture, our charged particle can move differently? Since we are dealing with electrons (-), they flow towards the positive region. So our electrons flow against the electric field, from bottom to top (- to...

Greater electric potential but less electric potential energy?? The picture in my book looks like this: 1. The electric potential at pt. B in the parallel-plate capacitor shown here is less than the electric potential at pt. A by 4.50V. The separation between pts. A and B is .120cm, and the...

If b is approaching 1 from the right, it seems like it would be very close to the number 1. Maybe it would be 1.00000000001 So 1/(1.00000000001 + 1) = 1/.00000000001 = +∞ I usually pay no attention to the - or + in the limit, but I see it's important! O_O Thanks!
