How can small molecules make their way past the cell membrane?
A. they pass through transmembrane channel proteins
B. they are hydrophobic
C. they are hydrophilic
Cell theory states that
A. life is spontaneously generated
B. New cells come only from pre-existing cells
C. cells can form from non-organic material
Animals store energy in a polymer composed of many glucose molecules called:
A. glycogen
B. cellulose
C. chitin
D. starch
A cell produces 36 ATPs per glucose, however, if you calculated the total energy in a glucose molecule, 90 ATPs should be generated. Why is this so?
A. Some of the energy is destroyed
B. Some of the energy is used to do work in the cell
C. Some energy is lost as heat
In animal cells the primary organelle that generates molecules of ATP is the

C. entropy
D. living energy
Glycolysis
A. uses oxygen
B. does not use oxygen
C. uses carbon dioxide
What are the inputs and the output molecules for respiration?
A. input sugar and oxygen; output carbon dioxide and water
B. input oxygen and water; output sugar and carbon dioxide
C. input carbon dioxide and water;output sugar and oxygen
Ans-1- entropy defines the randomness or disorderness of the system. Entropy increases as the disturbance/disorderness increases. Option C is correct.
Ans-2-small molecules which are polar/hydrophilic in nature are transported into the cells by either channel or carrier or transporter Protiens embaded embedded in the membrane. Option A is correct.
And-3- according to the cell theory given by Schleiden and Schwann the cell comes from pre-existing cells. Option B is correct.
Ans-4- polymer of glucose is called Glycogen, the major storage form of energy in animals.
Ans-5-in every process there is lost of some amount of energy. No any process till date is know which is 100% efficient and there is no loss of energy. During respiration some of the energy is lost as heat.
Ans-6- ATP is generated in mitochondria by oxidative phosphorylation.
Ans-7- osmosis is movement of water though the membrane into the cells by absorption. Option C is correct.
Ans-8- mitochondria is the cell organelle which is responsible for the respiration.
Ans-9- cellluer respiration is the process where the food molecules generally glucose is converted into ATP.
Ans-10- any moving object possesses kinetic energy within them.
Ans-11- glycolysis involve conversion of glucose into 2 molecules of pyruvate which does not require oxygen. Option B is correct.
Ans-12- sugar and oxygen are input compound while CO2 and water are the end/output products.
