Lipids
Carbon and hydrogen.
What are lipids primarily composed of?
Hydrogen bonds.
What type of bond is responsible for water’s unique properties?
stores genetic information.
What is the role of DNA in the cell?
Epithelial, connective, muscle, and nervous tissues.
What are the four main types of tissues?
Skeletal, cardiac, and smooth
What are the three types of muscle tissue?
Saturated fats.
What is the term for fats that contain no double bonds?
It can dissolve many polar substances
Why is water considered a good solvent?
single-stranded and contains uracil instead of thymine.
How does RNA differ from DNA?
To provide support and structure to the body.
What is the primary function of connective tissue?
To facilitate voluntary movement.
What is the primary function of skeletal muscle?
It has a hydrophilic head and hydrophobic tails, forming a bilayer in cell membranes.
What is the structure of a phospholipid?
7 (neutral).
What is the pH of pure water?
The process of copying DNA into mRNA.
What is transcription?
Simple columnar epithelium.
Name a type of epithelial tissue that is specialized for absorption.
Conducting electrical impulses throughout the nervous system.
What are neurons responsible for?
Steroids
What is a type of lipid that acts as a signaling molecule.
It helps regulate temperature in organisms and environments.
How does water's high heat capacity benefit living organisms?
It brings amino acids to the ribosome for protein synthesis.
What is the role of transfer RNA (tRNA)?
To generate force and facilitate movement.
What is the function of muscle tissue?
Involuntary and striated, versus voluntary and striated.
How does cardiac muscle differ from skeletal muscle?
It helps to maintain membrane fluidity and stability.
What is the role of cholesterol in cell membranes?
Its polarity allows it to interact with various substances, making it essential for biochemical reactions.
What is the significance of water being a polar molecule?
DNA is transcribed to RNA, which is then translated into proteins.
the central dogma of molecular biology.
It conveys information through electrical impulses.
Describe the role of nerve tissue in the body.
They support and protect neurons.
What is the role of glial cells in nervous tissue?
