What is the term for metabolic pathways that release stored energy by breaking down complex molecules?
This only the 50th time you ave heard this question............. Catabolic pathway
What do you call a process if it does NOT require oxygen?
anaerobic
What do you call a process that requires oxygen?
aerobic
This process releases carbon dioxide into the atmosphere.
cellular respiration geniuses
Type of fermentation used by our muscle cells.
lactic acid fermentation
The molecule that functions as the reducing agent (loses electrons) in a redox or oxidation-reduction reaction
Loses electrons ( becomes oxidized) and loses potential energy
When glyceraldehyde – 3 – phosphate (G3P) loses a hydrogen atom as the result of an oxidation-reduction reaction, the molecule becomes
HINT: OXDIATION- REDUCTION reaction
Also, if you needed the HINT for this, then you are in trouble.
Oxidized
Who is the krebs cycle named after?
Give me the other name for it.
A bloke named Kreb
This process releases energy from sugar for cellular processes.
cellular respiration
Carbon dioxide (CO₂) is released during which of the following stages of cellular respiration?
oxidation of pyruvate to acetyl CoA and the citric acid cycle
Name the four steps (according to your amazing teacher) of cellular respiration in order.
Glycolysis - Oxidation of Pyruvate- Krebs Cycle - Electron Transport Chain
How many ATP molecules does fermentation produce?
2 that were produced by glycolysis. 0 in fermentation itself
How many total ATP are made from one molecule of glucose in cellular respiration?
36
In addition to ATP, what are the end products of glycolysis?
NADH and Pyruvate
Where are the proteins of the electron transport chain located?
Inner membrane
What process is used by all living organisms to begin the breakdown of glucose regardless of the presence of oxygen or not?
glycolysis
When a molecule of NAD⁺(nicotinamide adenine dinucleotide) gains a hydrogen atom, the molecule becomes
this is child's play
reduced
What is the final electron acceptor at the end of the ETC?
oxygen
CO2 and H2O are waste products of this process.
cellular respiration
In cellular respiration, the energy for most ATP synthesis is supplied by
EXTREMELY IMPORTANT TO KNOW THIS
a proton concentration gradient (Hydrogen Ion gradient) across the inner membrane.
State the complete balanced formula for cellular respiration in words and symbols.
C6H12O6 + 6O2 --> 6CO2 + 6H2O + ATP
. The oxygen consumed during cellular respiration is involved directly in which process or event?
accepting electrons at the end of the electron transport chain
What is the first compound formed during the Krebs cycle?
Acetyl- CoA joins with oxaloacetate to form CITRATE.
CITRATE is the ANSWER
Which of the following enters the citric acid cycle (Kreb’s Cycle) and is formed, in part, by the removal of a carbon (CO₂) from one molecule of pyruvate?
Acetyl -CoA
When hydrogen ions (protons) are pumped from the mitochondrial matrix across the inner membrane and into the intermembrane space, the result is the
creation of a hydrogen ion motive force that will later move down its concentration gradient.
