Overview & Random
What is the chemical formula for glucose?
C6H12O6
This first stage of cellular respiration occurs in the cytoplasm and breaks glucose into pyruvate.
Glycolysis
This gas is required for aerobic respiration.
Oxygen
What is important about the structure of chloroplast and mitochondria?
super folded - reactions happen on and across membranes
This molecule is the main energy currency of the cell.
ATP
The purpose of cellular respiration is to convert this type of energy in glucose into this type of usable energy.
chemical energy --> ATP
This stage requires oxygen and occurs in the mitochondrial matrix.
Krebs Cycle
What stage of cell respiration does NOT require oxygen?
Glycolysis
Photosynthesis is to the _____________ as cellular respiration is to the _______________. (locations in the cell)
chloroplast ; mitochondria
ATP releases energy when...
the bond between the second and third phosphate is broken
What is happening to glucose and its energy throughout cellular respiration?
It is being BROKEN DOWN and the energy is captured by electron carriers to fuel the ETC --> ATP
What do the pyruvates become before entering the matrix? (1st step glucose splits in Glycolysis. ___________ enters the cycle of Krebs)
Acetyl - CoA
In what stage of Cellular Respiration is CO2 produced?
Krebs Cycle
This process stores energy in glucose; respiration releases it.
photosynthesis
In the ETC of Cellular Respiration, the energy carrier ________ (charged) donates electrons to fuel active transport and becomes _______ (dead)
NADH / NAD+
These two electron carriers charged in the Krebs Cycle feed the ETC.
NADH and FADH2
This stage produces the most ATP.
ETC
In what stage of cellular respiration is water produced?
ETC - O2 is the final electron acceptor
What products of photosynthesis are necessary for cellular respiration?
glucose & oxygen
The ATP breakdown in each stage of cellular respiration
2 glycolysis + 2 krebs + 30 - 34 ETC
~36 ATP
What do you expect to happen to the amount of CO2 you exhale right after a high intensity workout? Why?
INCREASE ; your cells break down more glucose for ATP, producing more CO₂ as waste
This molecule must be present for the ETC to function; without it, the chain backs up because the final electrons have no where to go.
Oxygen
Write the balanced equation for cellular respiration
C6H12O6 + 6O2 --> 6H2O + 6CO2 + ATP
What are two similarities in how cellular respiration and photosynthesis make ATP? (think about the specific processes)
ATP synthase facilitated diffusion
Gradient of H+
Use energy to pump H+
Summarize the transfer/transformation of energy that occurs in photosynthesis and cellular respiration
sun - (photosynthesis) -> glucose - (cell respiration) -> ATP
