The largest incisal embrassure is said to be btw Max lat incisor n canine
The Widest " " is said to be btw max canine n 1 premolar
I have seen both largest n widest being asked in question papers, yet not sure if both mean the same or the answers were wrong in the papers!!(I am not sure of the papers in which I found these, LL let u know in few days)

Yes,the widest incisal/occlusal in max arch is btw Canine-1stPremolar(Qpaper 1978,I-B)

Make sure what the Q is asking,LARGEST OR WIDEST!

2) Which configuration of mandibular 2nd PM (Y,X,H,U) has most trapezoidal shape occlusally?

Can anyone answer these questions?

 

[krasnodar]

Can anyone answer these questions?

It must be H or U ,,,,,H for sure ......Y (pentagon)


61% not sure

Reducing agent

 

[molar9]

Reducing agent

can you tell where exactly it acts as reducing agent.thanks

 

[firasoblast]

can you tell where exactly it acts as reducing agent.thanks

vit c is solely an antioxidant, or reducing agent. That is to say, vitamin C only has electrons to donate. It cannot, under any circumstances, take electrons away from surrounding tissues and act directly as an oxidizing agent. Only oxidized vitamin C (dehydroascorbate) is capable of receiving electrons.

 

[gaya]

can u please tell me where u found it as 61%

Muscle.

muscle( not sure)

can u please explain why do we say muscle here in the well fed state ?

 

[BigSmiles]

sorry guys, previous answer i gave was wrong. Answer is Liver.

 

[morphology]

sorry guys, previous answer i gave was wrong. Answer is Liver.

but liver can use it because it lacks succinyl coA acetoacetatecoA transferase.

 

[Kash]

which body tissue uses the ketone bodies in the well fed state?
brain
liver
muscle
adipose
rbc

The answer is Muscle. (Heart and Muscle use ketone bodies). Brain uses only incase of starvation or fasting. Liver does not use ketone bodies.

 

[chipotle]

The answer is Muscle. (Heart and Muscle use ketone bodies). Brain uses only incase of starvation or fasting. Liver does not use ketone bodies.

We are stressing upon the well fed state ...muscles use ketone bodies during fasting /starvation ...acetoacetate and beta hydroxybutyrate are hydroxylysd by muscles during starvation .

usually small amount of ketone bodies are produced everday.I think Muscle is the answer
