greater la convexity than mand canine
max canine
mand premolar



what is net charge glutamic acid in PH 1
+2

1. Did not understand the question.
2. -1 (acids are negatively charged, so I am guessing -1).
3. Don't know

acidophilia is correct.

G 1 is correct answer for previous question .The cells of same species
show high variabilty in contrast to S phase whose duration is constant
among the cells of same species but G2 also show variability less in contrast
to G1 .however if protien synthesis will not take place in G2 phase then cell will not undergo mitosis.

Ques 2 . what is net charge glutamic acid in PH 1
Ans. 0 (zero)
Because at pH 7 side chain of amino acids carry a charge which is negative incase of glutamic acid as well as aspartic acid. As the pH decreases, both these acids begin to lose their negative charges and at pH less than 4, they are mainly neutral. So. i think there will be no net charge.

Ques 3. Hydroxyl gp that participate in enzyme reaction
Ans. Serine
It belongs to polar group of amino acids. Polar groups interact with aqueous environment to form H-bonds. Moreover, Its a precursor for certain amino acids (which arginine is not though it is polar). So i think precursor and being polar helps the enzyme reaction.

Please correct me if i am wrong.

hi
i think the answer for 1st q is max canine, 3rd q , it is serine coz it has the hydroxyl group similar to ALL,
GLUTAMIC ACID HAS a pk value of 4, which is its PI, it a ph1 , , its a negative polar aminoacd,there is a formula to calculate the net charge ,iam trying to figure that out, its a pretty interesting q ,it will b nice if u guys work on it too!
and yes the conversion of proerythroblast to erthrocyte requires the acidophlic cytoplasm due to presence of carbonic anhydrase in the erythrocye. hope this helps,
most variable stage in cell cycle should be THE S phase ,synthetic phase where the dna replication, gene expression occurs, coz G1 and G2 are the cytoplasmic phases, mitosis is just the production of 2 similar daughter cells, plz correct me if wrong,

can anybody explain that
which region(means cervical 3rd, middle 3rd, oclusal 3rd) has the greatest labial convexity
in
1st max PM
2nd max PM
1st mandibular PM
2nd mandibular PM

& how do they differ, i mean which has the greater convexity as compared to each other ?
and out of the two caniines <mx & mnd> which has the greater la convexity?

HELLO
i think mandibular 1st premolare has the greatest labial convexity,the max premolars 1 and 2 has 2 cusps almost equally sharp[buccal and lingual],mandibular 1st pm has a big buccal/facial cusp and a poorly developed lingual cusp,mand 2pm has 3 well developed cusps

max canine has more labial convexity than mand canine
plz correct,if wrong

Glutamic acid has charge of +1 at ph 1(0-2.2)

Charge is 0 btween ph 2.2 -4.3, -1 btween ph 4.3-9.9

Charge of -2 above 9.9
