Answer 1

I can’t see the diagram — but carbon dioxide is produced during the Krebs cycle inside the mitochondrion. So pick the letter that labels the mitochondrion (the bean‑shaped organelle with inner folds/cristae). If you upload the picture or describe which letter is on that organelle I’ll confirm the exact letter.
