Protein Pathway
Where are proteins assembled?
Ribosome
What organelle controls the activities of a eukaryotic cell?
Nucleus
What is the main structure of the cell membrane?
Phospholipid bilayer
What organelle folds and processes many proteins?
Endoplasmic Reticulum
What organelle produces most of the cell’s ATP energy?
Mitochondria
What part of a phospholipid is attracted to water?
Phosphate head (hydrophillic)
Where are proteins modified, sorted, and packaged for transport?
Golgi Apparatus
What organelle breaks down waste and worn-out cell parts?
What membrane structures help control what enters and leaves the cell?
What transports proteins from the rough ER to the Golgi apparatus?
Vesicles
What organelle stores water, nutrients, and waste, and is especially large in plant cells?
Central vacuole
What molecule helps maintain cell membrane fluidity?
Cholesterol
Put the protein pathway in order: Golgi apparatus, ribosome, transport vesicle (2 of them), rough ER, nucleus.
Nucleus → Ribosome → rough ER → vesicle → Golgi → vesicle → cell membrane
What organelle is responsible for making lipids and helping detoxify harmful substances?
Smooth endoplasmic reticulum
What membrane protein has a carbohydrate chain attached and helps with cell recognition?
Glycoprotein
