Pre ap bio quiz 4.1-4.2

What is the primary difference between an ATP molecule and an ADP molecule?

• A molecule of ATP contains a ribose sugar, but a molecule of ADP contains deoxyribose.

• A molecule of ATP has three phosphate groups, but a molecule of ADP only has two.

• A molecule of ATP contains the nitrohenous base adenine, but a molecule of ADP contains the nitrogenous base uracil.

• There is no diffeence between the structure of an ATP molecule and that of an ADP molecule.

Which of the following is the correct function of chemosytosis?

• Help determine the locations of the nucleus and other organelles within the cell.

• Requires light energy Takes place in chloroplast (grana and stroma)

• provide energy for h+ ions transport

• Process where organisms that are deprived from sunlight use chemical energy to produce their own food to get energy.

Describe the relationship between energy stored in food and ATP.

• Chloroplast makes sugar during the process of photosynthesis converting light energy into chemical energy stored in glucose

• The energy in food can be harvested from its sugars (glucose), which is used in cellular respiration to produce ATP.

• ADP transfers energy from non- broken down food to cell processes

• There is no relation between them.

The two main parts of chloroplasts needed for photosynthesis are:

• The grana and the stroma.

• Water and sunlight

• Carbon dioxide and sugar

• Oxygen and sulfur

The stacks of coin-shaped, membrane-enclosed compartments in grana are called:

• chlorohyll

• stroma

• chloroplast

• thylakoids

What type of molecule makes the most ATP?

• only sugars

• lipids and carbohydrates.

• lipids and sugars

• sugars and carbohydrates

Which of the following is a fluid-like material that surrounds the grana inside a chloroplast?

• chlorophyll

• thylakoids

• stroma

• adenosine

Which of the following statemnts is false

• Carbohydrates are stored in large amounts in your body.

• The three most important molecules needed for the production of ATP are fats, proteins and carbohydrates.

• Carbohydrates are the molecules most commonly broken down to make ATP.

• The breakdown of the simple sugar glucose yields about 36 molecules of ATP.

The correct function of photosynthesis

• Is a process that captures energy from sunlight to make sugars that store chemical energy.

• A process by which some organisms use chemical energy - instead of light energy - as an energy source to make their own foods.

• Any of a class of small organelles, such as chloroplasts, in the cytoplasm of plant cells, containing pigment or food.

• Portion of photosynthesis that takes place in the stroma of chloroplasts and can occur in the dark. It uses the products of the light reactions to reduce CO2 to a carbohydrate.

The equation for the whole photosynthesis process is

• 6CO2 ---> C6H12O6 + 6O2

• CO2 + 6H2O ---> CHO6 + O2

• 6CO2 + 6H2O ---> C6H12O6 + 6O2

• CO2 + H2O ---> C6H12O6 + 6O2
