What is aerobic respiration
Process of producing cellular energy involving oxygen
Active transport
Active transport is the movement of a substance from low concentration to high concentration
(against its concentration gradient)
What does aerobic respiration produce how many
Roughly 36 ATP
Where does aerobic respiration occur
The mitochondria
What is the first step in aerobic respiration
Glycolysis
What is the second step in aerobic respiration
Citric acid cycle
Is the third process in aerobic respiration
Electron transport system
What is aerobic respiration used for
Working your muscles, growth and repair of cells, building a larger molecules from smaller ones, allowing chemicals are reactions to take place, absorbing molecules and active transport, keeping your body temperature constant, sending messages along or’s
Define anaerobic respiration
A form of respiration using electronic transports other than oxygen
Which cells use anaerobic respiration
Mostly in prokaryotes
What are the stages of anaerobic respiration
Glycolysis, Krebs cycle, electron transport chain
Product of anaerobic respiration
Carbon dioxide, ATP
Where is anaerobic respiration located
Mitochondria
What is ATP
ATP is considered to be the energy currency of life: high-energy molecule that stores the energy we need to do just about everything we do
Where is ATP synthesized
Mitochondria
Is the process by which the ATP is synthesized
Glycolysis
What is ADP
ADP is an ingredient for DNA. It is converted to ATP to release and store energy
Define chemosynthesis
In places in the world such as the seafloor where son cannot provide energy chemosynthesis is the process by which animals on the seafloor obtain energy through chemicals.
Define concentration gradient
The movement of high concentration to low concentration- kind of like diffusion
Define electron transport chain
Series of enzymes embedded in the membrane takes the electron carriers electrons and uses their energy for pumping protons increasing protein concentration
Define endocytosis
During endocytosisThe cell membrane folds into a pouch surrounding particles outside the cell.
What is formed to allow particles to move inside the cell during endocytosis
transport vesicle
Define exocytosis
The opposite of endocytosis. Particles are transported out of the cell. A vesicle containing Waste or cell products Ruth toward the cell membrane and fuses with it as the contents inside the vesicle are secreted
Defined facilitated diffusion
Also known as passive transport, The movement of a substance from low concentration to high concentration
