 FYAssertion: Krebs cycle occurs in cytoplasm of a cell and releases energy.
"keason: Glycolysis and kreb's cycle are the two steps of respiration. They both occur in
mitochondria and release energy.

~d aged people are affected by these diseases.
Reason: K washiorkar and marasmus are diseases affecting children below one year of age.

yH) Assertion: The product of combination of carbon dioxide and haemoglobin is termed as
carboxyhaemoglobin ·
Reason: RBCs carry carboxyheamoglobin from the tissue ·cells to blood capillaries, hence
carbon dioxide is exhaled out. ·
