(21 cards)
What is Oxidation?
Hint: OIL RIG
LOSS of electrons or hydrogen, GAIN of oxygen
What is Reduction?
HINT: OIL RIG
Gain of electrons or hydrogen, LOSS of oxygen
What is cellular respiration?
the process that converts chemical energy of glucose into the chemical of ATP, which powers life
What are the 3 processes that cellular respiration provides ATP to?
Active transport
Phagocytosis
Muscle contractions
What does the matrix do in the mitochondria?
Contains protein and chemical for breaking down glucose into ATP
What does the Cristae do in the mitochondria?
increases surface area to produce more ATP
What is Phagocytosis?
the intake of large food particles
What are the two types of cellular respiration?
Aerobic and Anaerobic respiration
What are the three parts of cell respiration?
Glycolysis
Krebs cycle
Electron transport chain (ETC)
What does Glycolysis take place?
Cytoplasm
What is Glycolysis?
the first step in cell respiration where glucose is broken down into two pyruvate. It occurs in the cytoplasm and oxygen is not required
What is the kerb cycle?
Makes as much high energy NADH and FADH2 from the broken down glucose (Acetyl CoA). the NADH and FADH are then used in ETC to make ATP
Where does the Krebs cycle take place?
mitocondrial matrix
where does the electron transport take place?
inner membrane of the mitochondria called CRISTAE
What is the other name for the Pre-krebs cycle?
Pyruvate oxidation
What does there Pyruvate oxidation do?
It covers the pyruvate for the Krebs cycle by converting the 2 pyruvate into 2 Acetyl CoA. then it enters mitochondria
what does the ETC do?
NADH and FADH2 are split to produce high energy electrons, these electrons then power active transport of H+ from mitochondrial matrix into the inter membrane space, where H+ accumulate, the H+ want to gonaturalkly from high to low concentration so this will power the …………………………….not done
What happen to the two H+ ions after chemiosmosis when they are released from the ATP synthase?
the two H+ ions bond with oxygen to from water
How much ATP is produced by glycolysis?
2 ATP
How much ATP is produced by thee Krebs cycle?
2 ATP
How much ATP is produced by ETC?
30-34 (can vary with movement which requires energy
