Question

what is the starting molecule of glycolysis?
glucose
pyruvic acid
adp
water
this structure is a
mitochondria
chlorophyll
chloroplast
plant cell

Explanation:

• Glycolysis is the metabolic pathway that breaks down glucose. Pyruvic acid is the end - product of glycolysis. ADP is involved in energy transfer (as a precursor to ATP), and water is not the starting molecule.
• Chloroplasts are double - membrane - bound organelles with thylakoid stacks (grana) inside. Mitochondria have a different structure (cristae instead of thylakoid stacks). Chlorophyll is a pigment found within chloroplasts, and a plant cell is a whole cell (much more complex than the shown structure).

Answer:

• For the first question: glucose
• For the second question: chloroplast
