Cellular Respiration Study Guide Flashcards
What happens during cellular respiration?
Cells release chemical energy from sugars to produce ATP in the presence of oxygen
ATP stands for
adenosine triphosphate
Source of energy for use and storage at cellular level
ATP
Cellular respiration is an ___ process
Aerobic (it needs oxygen in order to take place)
Where does cellular respiration occur in
mitochondria (powerhouse) make most of the cells ATP
A mitochondrion cannot make ATP directly from the food you eat. True or False?
True because food must be broken down into glucose and that gets broken down too
What does glycolysis do?
splits a molecule of glucose into three carbon molecules of ATP.
where does glycolysis take place?
Glycolysis takes place in the cytoplasm a anaerobic process
Where are the products of glycolysis broken down in?
mitochondria to make more ATP molecules
1st part of cellular respiration
glycolysis, takes place in the cytoplasm- cellular respirations remaining parts occur in the mitochondria
2nd part of cellular respiration
Krebs cycle (citric acid cycle) occurs in the matrix of a mitochondrion
what happens during the Krebs cycle?
three-carbon molecules from glycolysis are broken down
what does an electron transport chain made of proteins need?
energy carrying molecules and oxygen
up to ___ ATP molecules made from the breakdown of ___ molecule of glucose: ___ ATP from glycolysis + 34 or 36 ATP from cellular respiration in the mitochondria
-38
-one
-2
(Plant and animal cells) out of the two which one carry’s out photosynthesis and cellular respiration?
Plant cells
