Q.3
Which statement is wrong for Krebs' cycle ?
There is one point in the cycle where FAD+ is reduced to FADH2
During conversion of succinyl CoA to succinic acid, a molecule of GTP is synthesised
The cycle starts with condensation of acetyl group (acetyl CoA) with pyruvic acid to yield citric acid

Q.7
What is the correct equation for cellular respiration?
6O2 + C6H12O6 -> 6CO2 + 6H2O + Energy

helps maintain the fluidity of cell membranes
Q.10
In which way are photosynthesis and cellular respiration different?
Cellular respiration stores ATP, while photosynthesis releases ATP.
Cellular respiration produces oxygen, while photosynthesis uses oxygen.
Photosynthesis releases energy, while cellular respiration stores energy.
