Thea - Cytology Flashcards
Adipocytes are specialized cells that store fats in the form of:
Triglycerides
Which molecules are the primary components of cell membranes and create a lipid bilayer structure?
Phospholipids
In addition to cell membrane structure, what important role do phospholipids play in cellular functions related to signaling?
Serve as precursors for signaling molecules
Which of the following statements are true about Phospholipids?
Phospholipids are amphipathic molecules.
Phospholipids are composed of a hydrophilic head and two hydrophobic tails.
Phospholipids are important components of cell membranes.
How many enzymatic steps are involved in the glycolytic pathway?
Ten
Fill in the blank: _____ interact to generate force and movement within cells
Contractile proteins
Which of the following statements are true about the Backbone of RNA and DNA?
The backbone provides structural support for the genetic material.
How does the regulation of glycolysis differ from that of the citric acid cycle in terms of ATP availability?
Glycolysis is stimulated by low ATP levels, while the citric acid cycle is inhibited by high ATP levels, reflecting their roles in energy demand.
How do glycoproteins and lipoproteins differ in their primary function within cellular structures?
Glycoproteins primarily function in cell recognition and signaling due to their carbohydrate components, while lipoproteins primarily serve as transport molecules for lipids in the bloodstream.
What is the name of the protein that is involved in maintaining cell structure and enabling cell movement?
Actin
