Enzymes
What is the main function of enzymes?
To decrease the activation energy needed for a reaction to occur and speed up the reaction.
What is the formula for photosynthesis?
6CO2+6H2O+light energy→C6H12O6+6O26
What is the formula for Cellular Respiration?
C6H12O6 + 6O2 -> 6CO2 + 6H2O
What are redox reactions?
Reactions that have an oxidation (OIL) and reduction (RIG) stage.
What are the 2 types of anaerobic respiration (fermentation)?
Lactic acid and alcohol fermentation
What are the two types of pathways that make or break molecules?
Catabolic - breaking large molecules into smaller molecules
Anabolic - building large molecules from small molecules
What is the byproduct of the light reaction that is released back into the environment?
Oxygen
When I say that NADH and FADH2 are energy-carrying molecules, what does that mean that they have in them? (Hint: don't put energy)
electrons!
What are the 2 forms of energy carrying molecules that we see in both processes?
ATP and NADPH
Why is it valuable that plants absorb different wavelengths?
It increases their fitness allowing them to photosynthesize using different wavelengths of light
Describe the active site
The active site is where the substrate would bind to the enzyme
What wavelength of light does PSII take in? What wavelength of light does PSI take in?
PSII is at 680nm and PSI is at 700nm
Write how much ATP is made during glycolysis, krebs cycle, and ETC
2, 2, 32
Which cell type can do both processes and why?
Plant cells because they have chloroplasts and mitochondria
Who is Ms. K's favorite country singer?
Morgan Wallen
Describe the difference between exergonic and endergonic reactions.
Exergonic reactions release energy and yield simple products.
Endergonic reactions absorb energy and yield complex molecules.
What are the 3 main stages of the Calvin Cycle?
1. Carbon Fixation
2. Reduction of G3P
3. Regeneration of RuBP
Describe the role of chlorophyll in the photosystems
Absorb light energy (photons) and generate ATP and NADPH
What molecule is produced in Cellular Respiration that is needed to start the process of light independent reactions in photosynthesis?
Carbon Dioxide
How long has Ms. K been teaching for?
3 years
What does enzyme-substrate complex mean?
A substrate has bonded to the active site of the enzyme
Explain the role of Rubisco in the Calvin Cycle
It catalyzes the reaction of carbon fixation so the atmospheric Carbon dioxide can be usable
How does the ATP synthase work?
The H+ ions that are moving because of the electrical current in the inner membrane are moving them into the ATP synthase which acts like a rotor to pump them across the membrane. The energy from them being pumped across the membrane helps ADP and Pi get bonded together.
What molecule is split apart to make hydrogen ions?
Water is split to produce H+ for the electron transport chain
Genetically speaking, organisms have variation in ____________ that allows them to increase their fitness as a population
genes/alleles
