Great image but the concentration of glucose inside the enterocyte cell needs to be represented as higher than inside the lumen of sm. intestine.
If not, it inherently is not an image of secondary active transport. So I fixed the image to have more glucose in the enterocyte than in the lumen.
You might double-check, though the image appears to be correct to me. One is going down its concentration gradient (sodium), and the other is going up the gradient (glucose), which is the point of the card and the image. Sodium-glucose transporter moves glucose against its concentration gradient, rather than down it, by definition. Image also taken from 'secondary active transport' labeling from wikipedia.
I believe the image to be correct as-is.
