Define "cellular respiration"
The process by which cells obtain energy from glucose
What is the function of a Lysosome?
To break down and recycle macromolecules
Where does Glycolysis occur?
In the cytoplasm
What are the reactants of Glycolysis? (What goes in?)
What are the products of Glycolysis?
2 Net ATP
Where does Pyruvate Processing occur?
In the matrix of the mitochondria
From each molecule of glucose, the cell obtains...?
Where will hydrophilic proteins be synthesized?
Hydrophilic proteins will be synthesized in the cytoplasm
Where will proteins that are intended to go outside of the cell/embedded in the cell membrane be synthesized?
In the Rough ER
Where will the proteins of cellular respiration/glycolysis be synthesized?
By ribosomes in the cytoplasm
What is Glycosolation?
the protein is folded and modified by adding carbohydrates
What is the function of organelles in eukaryotic cells?
Organelles increase the efficiency of the biochemical reactions that occur in the cell
Testosterone is a steroid hormone that is responsible for the development of the male reproductive system. Which of the following organelles will be found abundantly in the cells of human testes?
CFTR gene encodes for the CFTR transmembrane protein. Where is this protein synthesized?
Hexokinase is an enzyme that catalyzes the first reaction of glycolysis. Where will hexokinase be synthesized?
Hexokinase will be synthesized in the cytoplasm.
What is the function of microtubules?
Microtubules are used as the "railroad tracks" for vesicle transport.
What are the three types of molecular structures that make up the cytoskeleton?
What is the function of peroxisomes?
Peroxisomes are responsible for the oxidation of fatty acids.
Which organelle is responsible for protein/lipid packaging and sorting?
The Golgi Apparatus
Which organelle is responsible for lipid synthesis?
the Smooth ER
Which organelle is responsible for protein synthesis?
the Rough ER
Exergonic reactions are...
Catabolic, and they release energy by breaking bonds
Endergonic reactions are...
Anabolic, and they absorb energy by forming bonds
During which two stages of Cellular Respiration does Substrate Level Phosphorylation occur?
Substrate level phosphorylation occurs in glycolysis and the Krebs Cycle
all enzymes are
What happens to a reaction if there is too much kinetic energy?
If there is too much kinetic energy, the reaction will be interrupted
What happens to a reaction if there is not enough kinetic energy?
If there is not enough kinetic energy, the reaction will not take place
the reactant upon which an enzyme works
combinations of old and new bonds that are formed when reactants collide
