It is possible to draw something like the figure below using TikZ 
or any other Latex package?

You can certainly create an image with TikZ or PSTricks. But in my opinion it is too complicated as image. I am often very brief, especially in my questions/answers. I believe that with InkScape you could convert your image to a TikZ or PSTricks code if I remember correctly and save a lot of time.

@Sebastiano It is a good point, but I don't think this is too much for TikZ really. When I read the title I was worried the OP wanted to draw something more like en.wikipedia.org/wiki/Alpha-amylase#/media/… and came here with the intention of saying the same thing as you! :P But this cartoon is well within TikZ's capabilities I think, if one can be bothered

I'd use pics for that. This allows you to draw the same thing, possibly with some variation, over and over. In this example, I use
draw (1.2,2.9) pic[rotate=25] Enzyme B=3;
Here, Enzyme B is the second of your enzymes, and 3 means both receptors (?) are filled. If I would had chosen 0, 1 or 2 instead, none, the lower one or the upper one would have been filled. (1.2,2.9) is the coordinate, and as you see, you can rotate the pic (or subject it to other transformations like scale for instance). I have left a few enzymes to be placed for you as an exercise. ;-) (EDIT: Made the radii of the bummies a bit smaller and adjustable.)

just for fun and recognizing that marmot's code is really practical, a version with other options that require manual positioning, to get the result as close to the example; the enzymes have conditional parts derived from marmot's answer, but these are activated or deactivated with 0 or 1 to avoid defining 4 states.

Since that is just a very quick answer, here are just the “styles“ that are necessary:
documentclass[border=5pt,tikz]standalone
begindocument
begintikzpicture[green!70!black]
beginscope[rotate=75]
draw (0,0) arc(0:180:.5);
draw (1,0) arc(0:180:.5);
draw (-1.5,.5) arc(180:270:.5);
draw (-1.5,.5) --+ (0,.5) arc(-180:-270:.5) --+ (2,0);
draw (1.5,1) arc(0:90:.5);
draw (1.5,1) --+ (0,-.5) arc(0:-90:.5);
endscope
fill[yshift=-4cm,xshift=-1.7cm,green!70!black!50] (0,2) -- (0,0) --+ (1.5,0) --+ (1.5,.3) --+ (1.1,.3) --+ (1.1,.9) --+ (1.5,.9) --+ (1.5,1) -- (1.1,1) --+ (0,.7) --+ (.4,.7) --+ (.4,1) -- cycle;
beginscope[xshift=-1.2cm,yshift=-5cm]
draw[very thick,red!70!black,fill=red!70!black!80] (0,0) circle(.5);
draw[very thick,red!70!black,fill=red!70!black!80] (.5,0) circle(.5);
draw[red!70!black!80,fill=red!70!black!80] (0,0) circle(.5);
draw[red!70!black!80,fill=red!70!black!80] (.5,0) circle(.5);

I'd use pics for that. This allows you to draw the same thing, possibly with some variation, over and over. In this example, I use
draw (1.2,2.9) pic[rotate=25] Enzyme B=3;
Here, Enzyme B is the second of your enzymes, and 3 means both receptors (?) are filled. If I would had chosen 0, 1 or 2 instead, none, the lower one or the upper one would have been filled. (1.2,2.9) is the coordinate, and as you see, you can rotate the pic (or subject it to other transformations like scale for instance). I have left a few enzymes to be placed for you as an exercise. ;-) (EDIT: Made the radii of the bummies a bit smaller and adjustable.)

just for fun and recognizing that marmot's code is really practical, a version with other options that require manual positioning, to get the result as close to the example; the enzymes have conditional parts derived from marmot's answer, but these are activated or deactivated with 0 or 1 to avoid defining 4 states.

Since that is just a very quick answer, here are just the “styles“ that are necessary:
documentclass[border=5pt,tikz]standalone
begindocument
begintikzpicture[green!70!black]
beginscope[rotate=75]
draw (0,0) arc(0:180:.5);
draw (1,0) arc(0:180:.5);
draw (-1.5,.5) arc(180:270:.5);
draw (-1.5,.5) --+ (0,.5) arc(-180:-270:.5) --+ (2,0);
draw (1.5,1) arc(0:90:.5);
draw (1.5,1) --+ (0,-.5) arc(0:-90:.5);
endscope
fill[yshift=-4cm,xshift=-1.7cm,green!70!black!50] (0,2) -- (0,0) --+ (1.5,0) --+ (1.5,.3) --+ (1.1,.3) --+ (1.1,.9) --+ (1.5,.9) --+ (1.5,1) -- (1.1,1) --+ (0,.7) --+ (.4,.7) --+ (.4,1) -- cycle;
beginscope[xshift=-1.2cm,yshift=-5cm]
draw[very thick,red!70!black,fill=red!70!black!80] (0,0) circle(.5);
draw[very thick,red!70!black,fill=red!70!black!80] (.5,0) circle(.5);
draw[red!70!black!80,fill=red!70!black!80] (0,0) circle(.5);
draw[red!70!black!80,fill=red!70!black!80] (.5,0) circle(.5);
endscope
endtikzpicture
enddocument
Here is the output:

You can certainly create an image with TikZ or PSTricks. But in my opinion it is too complicated as image. I am often very brief, especially in my questions/answers. I believe that with InkScape you could convert your image to a TikZ or PSTricks code if I remember correctly and save a lot of time.

@Sebastiano It is a good point, but I don't think this is too much for TikZ really. When I read the title I was worried the OP wanted to draw something more like en.wikipedia.org/wiki/Alpha-amylase#/media/… and came here with the intention of saying the same thing as you! :P But this cartoon is well within TikZ's capabilities I think, if one can be bothered
