Ans.1. (A). 34 ATP.

Electron transport chain is defined as a series of reactions that involves transfer of electrons from one molecule to another via redox reactions and transfer of protons across the mitochondrial membrane. The transfer of protons make a proton gradient that drives energy for ATP synthesis.

Thus, the correct answer is option (A).  

Ans.2. False.

Cellular respiration is a metabolic reaction that involves breakdown of complex organic molecules, such as glucose to provide energy in the form of ATP molecules. Glucose is consumed in cellular respiration, instead of being produced.

Thus, the given statement is 'false.'

Ans.3. (C) glycolysis, Krebs cycle (citric acid cycle), Electron transport chain

Cellular respiration takes place in three steps, which include glycolysis, Krebs cycle (citric acid cycle), and electron transport chain. During glycolysis, glucose molecule converts into pyruvate that enters into Krebs cycle as acetyl co-enzyme A. During Krebs cycle, NADH and FADH2 are produced that enter electron transport chain to make ATP molecules.

Thus, the correct answer is option (C).

Ans.4. (A)  Pyruvate.

Glycolysis is defined as first step of cellular respiration that involves breakdown of glucose molecules to make energy releasing molecules, ATPs. Each glucose molecule produces two molecules of pyruvate as end products.

Thus, the correct answer is option (A).

Ans.5. (B) CO2.

Krebs cycle includes a series of reactions that helps to generate energy by forming NADH and FADH2 molecules. During krebs cycle, one molecule of acetyl co-enzyme A gets oxidized to produce 6 NADH and 2 FADH2 molecules and produce water and two carbon dioxide molecules.

Thus, the correct answer is option (B).

the dna of humans and mice is almost 92% similar. this similarity indicates that . mice have a tail, while humans have a tailbone. the tailbone is a structure in humans.yes it's true.

i think its y= -4x-14
