Cellular Respiration
Powerhouse of the cell is
Mitochondria
• oxygen is present two-step process known as
•If oxygen is NOT present, then the cell will go through?
•If oxygen is present, then the cell will go through a two-step process known as?
•If oxygen is NOT present, then the cell will go through ?
all of the chemical reactions within each cell of an organism.
Metabolism
Enzymes are very specific. Truth or False
Enzymes are very specific.
The entire series of events that a cell goes through to grow and divide.
What is the cell cycle?
Glucolysis mean
Break down of sugar
Citric Acid Cycle (aka Krebs Cycle)
Location:
Location = Mitochondrial Matrix
Catabolic and Anabolic are?
Catabolic: break down larger molecules into simpler compounds à a release in energy = exergonic
Anabolic: build larger molecules from smaller ones à requires consuming energy to do it = endergonic
speed up reactions
Catalyst
The two main stages of the cell cycle.
What are interphase and mitosis (M phase)?
Glycolysis produces
•Produces 2 ATP total and a 2 NADH.
Electron Transport Chain
Location =
Location = Inner membrane of the mitochondria
Breaking a bond requires energy to be
Forming a bond allows energy to be
Breaking a bond requires energy to be absorbed.
Forming a bond allows energy to be released
This is what enzymes do to activation energy.
It lowers it.
The final process that divides the cytoplasm.
What is cytokinesis?
End product of glycolysis
Pyruvate
In the absence of oxygen, a cell will go through anaerobic respiration and a process called
fermentation.
Endothermic:
Exothermic:
Endothermic: absorbs energy (in the form of heat or light)
Ex. Photosynthesis
Exothermic: releases energy (in the form of heat or light)
Ex. Cellular Respiration
Competitive Inhibitor
slows down reaction
The correct order of mitosis.
PMAT
Cellular respiration equation?
C6H12O6 + 6O2 -> 6CO2 + 6H2O + energy
•There are two main types of fermentation:
–Lactic acid fermentation
–Alcohol fermentation
•Aerobic Respiration = 36-38 ATP
–2 ATP from
–2 ATP from
–34 ATP from
•Aerobic Respiration = 36-38 ATP
–2 ATP from Glycolysis
–2 ATP from Krebs Cycle
–34 ATP from Electron Transport Chain
When the shape of an enzyme changes and it stops working entirely.
Denature
This condition occurs when cells ignore checkpoints and divide uncontrollably.
