Living Environment Unit 2 Review
Place in the chloroplast where photosynthesis takes place.
Chlorophyll
In what organelle does photosynthesis take place?
Chloroplast
What breaks down things during chemical reactions?
Enzymes
Why is ATP important?
It is used as a direct source of energy.
The shape of an enzyme determines what?
It's function.
Why is more oxygen produced during the day than at night?
Photosynthesis needs the sunlight to function.
Within a plant cell, the glucose formed as a result of photosynthesis may be used directly as ________??
an energy source during cellular respiration
What is produced by cellular respiration?
carbon dioxide, water, and ATP (energy)
What is needed for photosynthesis?
carbon dioxide, water, and sunlight
ATP is a compound that is synthesized when
energy stored in chemical bonds is released during cellular respiration
Maintaining an appropriate temperature is beneficial to an organism because
enzymes need a proper range of temperatures to catalyze vital reactions
What are the reactants of cellular respiration?
glucose and oxygen
What is produced by photosynthesis?
glucose and oxygen
Creatine, a popular nutritional supplement, is used to decrease fatigue by increasing ATP in muscle cells. The cell structure directly responsible for the increased production of ATP in human muscle cells is the
mitochondria
In what organelle does cellular respiration occur?
mitochondria
What type of macromolecule is an enzyme?
protein
A fully functioning enzyme molecule is arranged in a complex three-dimensional shape. This shape determines the
specific type of molecule it interacts with during a reaction
What is a catalyst?
substance that speeds up the rate of a chemical reaction
An enzyme that rapidly breaks down a protein molecule in the stomach may break down that same protein much more slowly in the small intestine or mouth because
the stomach may have a more suitable environment for the enzyme to work
synthesize
to make
