Unit 5 Review

What is the basic energy source for CELLS?

• Sucrose

• Glucose

• ATP

• ADP

Where is the energy stored in an ATP molecule? Must be VERY specfic

• The bond between the 2nd and 3rd phosphate

• The bond between the 1st and 2nd phosphate

• In the base

• In the sugar molecule

An ATP molecule is made up of 3 things: Must be specific and give actual name.

• 3 phosphates, Sugar, Ribose

• 2 phosphates, adenine, Ribose

• 3 glucoses, adenine, Ribose

• 3 phosphates, adenine, Ribose

Which process below creates the most ATP and about how many ATP does it produce in total? (Write letter and #)

• Photosynthesis

• Fermentation

• Cellular Respiration

• Anaerobic Respiration

True or False: The amount of cellular respiration, and ultimately ATP, will INCREASE as sugar (glucose) concentration increases. 

• True

• False

Answer explanation

because sugar (glucose) is a reactant of cellular respiration, so as you add more reactant you should get more product.

Which of the following does not effect the rate of photosynthesis

• Temperature

• Amount of Light

• Amount of CO2

• Amount of Glucose

What is the primary source of energy for photosynthesis?

• ADP

• ATP

• Sunlight

• Glucose

True or False: During photosynthesis, light energy absorbed by the plant powers a reaction that produces carbon dioxide and water.

• True

• False

Answer explanation

It is converted into chemical energy (glucose), which the plant stores (as starch).

What are the products of photosynthesis and in what amount?

• 1 Glucose and 6 CO2

• 1 Glucose and 6 oxygen

• 1 Glucose and 6 ATP

• 1 ATP and 6 oxygen

If you are viewing a unicellular organism under a microscope, what is the MAIN way you quickly tell if it’s photosynthetic?

• You look for the presence of chloroplasts

• You look for the presence of mitochondria

• You look for the presence of a cell membrane

• You look for the presence of a nucleus
