What is glycolysis?
The process of breaking down carbohydrates, starting with hexoses and ending
with pyruvate.
What is the primary starting material for glycolysis?
Glucose.
,What is pyruvate's role in cellular metabolism?
It can be further processed to acetyl-CoA for energy extraction.
What is the significance of acetyl-CoA in metabolism?
It is a common molecule that allows cells to extract energy from both
carbohydrates and lipids.
What happens to ATP produced in the mitochondria?
It moves out to the outer membrane and then into the cytosol.
What is the structure of NADH?
A molecule containing two nucleotides joined through phosphate groups.
What is the function of transporters in the mitochondria?
They move specific molecules across the mitochondrial membrane.
What is the citric acid cycle's role in energy production?
It generates NADH, which is used in the electron transport chain to produce ATP.
What is the significance of coupling in cellular processes?
, It connects the energy released from ATP breakdown to processes that would not
otherwise occur.
What is the difference between NADH and FADH2?
They are both electron carriers but have different structures and interactions with
proteins.
What is the end product of glycolysis?
Pyruvate.
What is the role of enzymes in metabolic pathways?
They catalyze reactions to convert substrates into products.
How do cells regulate metabolic pathways?
By controlling the rate of enzyme-catalyzed reactions.
Where does glycolysis occur?
In the cytosol.
What are the two phases of glycolysis?
