Phosphate group
Cholestrol
The absence of a double bond within the fatty acid carbon chain makes it unsaturated.
What is the role of cholesterol in the membrane?
Help keeps the shape of the membrane circular
Attachment site for glycogen molecules
Enzyme attachment site
Role in membrane fluidity
What is the role of microfilaments in the epithelial cell in the small intestines?
The microfilaments increase the cell surface area during meiosis and mitosis
The microfilaments provide a stiff surface for cellular respiration to happen in the small intestines
The microfilament increases the surface area of cell allowing the microvili projections to stand upright and absorb nutrients
What are the four cell types that move on their own?
Sperm
Egg
Red Blood Cells
White blood Cells
Fibroblast
Skin
Epithelial Cells
How do motor neurons send messages/ impulses to other cells that are far away?
The long microtubules in the motor neuron cell can overcome the distance by stretching the cell and having mitochondria through out the axon to deliver the action potential in the cell.
The long microtubules in the motor neuron cells can overcome the distance by stretching the cell and having it connect to the other cell by cell - to - cell adhesion
The long microtubules in the motor neuron cell can overcome the distance by stretching the cell long enough to reach the spinal cord
During ATP production, when the electron is passing through the complexes in the ETC 75% of the energy is lost as heat.
Lipids are not defined by a single monomer, lipids have various structures and lipids are defined by solubility in water.
How are glands formed during embryonic development?
Formed by pockets of epithelial tissue that dip inward from the surface and develop secretory abilities.
Formed by mass production of epithelial cells that ball into a gland
Formed by nerve cells that develop secretory abilities.
What are the two categories of glands?
enocrine
endocrine
mesocrine
exocrine
mendocrine
ecocrine
Sweat glands and glands that secrete digestive juice are examples of the exocrine system.
