What is the main product of photosynthesis?
Glucose
What is the main product of cellular respiration?
ATP
What are the four biomolecules?
Proteins
Carbohydrates
Lipids
Nucleic acids
What are the two types of Nucleic acids
DNA
RNA
Which process converts light energy, carbon dioxide, and water into glucose and oxygen?
Photosynthesis
Which process converts glucose and oxygen into water, carbon dioxide, and ATP?
Cellular respiration
Where do heterotrophs get glucose?
From the food they eat
Where on the enzyme does a substrate bind?
Active site
What biomolecule is consumed during cellular respiration?
Carbohydrate (glucose)
Explain the Endosymbiosis theory
Endosymbiosis says that Mitochondria and Chloroplasts were once free living organisms (bacteria) that were swallowed by a larger cell. The host and symbiote became intertwined and now cannot function without the other (forming a eukaryotic cell)
Where do autotrophs get glucose?
Through photosynthesis
If glucose suddenly didn't exist, what process(es) would be affected?
A. Photosynthesis
B. Cellular Respiration
C. Both
D. Neither
What is the relationship between photosynthesis and cellular respiration?
They form a cycle, where the products of one become the reactants of the other.
If a cell is less organized, has a flagella, and has DNA in the cytoplasm, what type of cell is it?
Prokaryote
How do we define a cell?
By where it's genetic material is located
Prokaryotic- no nucleus, DNA free-floating in the cytoplasm
Eukaryotic- DNA found in the nucleus
What is the biomolecule that is a primary component of the cell membrane
Lipids
What are the functions of lipids?
Insulation
Thermoregulation
Plasma membrane of cell (and other membranes in organelles)
What are three membrane bound organelles found only in Eukaryotic cells?
Mitochondria
Nucleus
Chloroplasts
Golgi
ERs
Explain how glucose is involved in both cellular respiration and photosynthesis
Glucose is a product of photosynthesis (made) and a reactant in cellular respiration (broken down)
Explain the role of inhibitors and activators on an enzyme
Inhibitors bind to either the active site directly (competitive) or a secondary location and change the conformation. Both stop enzyme activity
Activators bind to a secondary site on the enzyme and change the shape of the active site for the substrate to bind successfully, starting the reaction.
