What organelle is the main site of cellular respiration in eukaryotic cells?
What is the Mitrochondria?
What is the first stage of cellular respiration?
What is glycolysis?
What molecule is the main energy-carrying molecule used by cells?
What is ATP?
What sugar molecule is broken down during cellular respiration?
What is glucose?
What gas must be available for aerobic cellular respiration?
What is oxygen?
What fluid-filled space inside the mitochondrion that produces Carbon Dioxide for the Krebs cycle?
What is the Mitochondrial Matrix?
A cell has plenty of glucose but no oxygen. Which stage can still produce a small amount of ATP?
What is glycolysis?
What molecule forms when ATP loses a phosphate group?
What is ADP?
What gas do cells release as a waste product of cellular respiration?
Carbon Dioxide
True or false: Plants perform cellular respiration.
True
Where in the mitochondrion does the electron transport chain occur?
What is the inner Mitochondrial Membrane?
During what stage is most carbon dioxide released?
What is the Krebs Cycle?
What happens to energy when ATP is converted into ADP and phosphate?
Energy is released and can be used for cellular work.
What gas is required for aerobic cellular respiration?
What is oxygen?
What is the balanced overall equation for aerobic cellular respiration?
Glucose + oxygen → carbon dioxide + water + energy (ATP).
What is the name of the fluid inside the cell where glycolysis takes place?
What is the Cytoplasm?
What stage uses electrons to power a proton gradient that helps produce ATP?
What is the Electron Transport Chain?
What happens to ATP when a cell needs energy to do work?
ATP loses a phosphate group and releases usable energy.
BONUSSSS!!!
Why do cells need energy even when an organism is resting?
Cells still need ATP for processes such as transport, repair, and maintaining homeostasis.
A runner's muscle cells need more ATP during a sprint. What process helps them make ATP from glucose?
What is cellular respiration?
Why do muscle cells generally contain many mitochondria?
They need large amounts of ATP to power muscle contractions.
Put these stages in order: Krebs cycle, glycolysis, ETC
Glycolysis, Krebs Cycle, ETC
What is chemical energy?
a form of potential energy stored in the bonds between atoms and molecules of chemical substances.
What three main products are formed by aerobic cellular respiration?
What is ATP, CO2 and H2O
A cell has glucose and oxygen available. Explain why it needs to make ATP instead of using glucose directly for every activity.
ATP provides a readily usable energy source that powers cellular processes.
