Respiration Flashcards
(31 cards)
Why do cells need energy? ⚡️ ATP
Cell division 🧫
Protein synthesis 🍗
Muscle cell contraction 💪
Transition of nerve impulses 🧬
Why is respiration required?
To release the chemical energy stored as glucose 🍭
What is respiration?
A series of enzyme controlled reactions 🎮
What forms ATP?
ADP+Pi 🥧
What happens when ATP releases pi?
Energy is released ⚡️
What happens to the energy when glucose is broken down?
Energy is stored as ATP 🎁
What is the first stage of respiration called?
Glycolysis
Where does glycolysis take place in animals and plants?
Cytoplasm
Does glycolysis take place with AND without oxygen present?
Yes 🥳
During glycolysis stage 1, what is glucose broken down into?
2 molecules of pyruvate
What does the breakdown of glucose in stage 1 release?
2 ATP 🎁
What does the outcome of stage 2 in respiration depend on?
Presence of oxygen 💨
Type of cell
Does aerobic respiration take place with or without oxygen?
With
Does fermentation in animals take place with or without oxygen?
Without
Does fermentation in plants take place with or without oxygen?
Without
Where does aerobic respiration take place?
Mitochondria
What happens during aerobic respiration?
Pyruvate broken down into carbon dioxide + water
How much ATP does aerobic respiration produce?
Many ATP
What do cells that require a lot of energy, have high numbers of, to allow them to perform aerobic respiration? ✍️
Mitochondria 🐾
What do muscle cells require energy for? 💪
Contractions
Where does fermentation occur?
Cytoplasm
Does fermentation require oxygen?
No
What are the pyruvate molecules converted to in fermentation in animals?
Lactate 🥛
What is fermentation in fungi the same as?
Fermentation in plants 🌱
