1. What are the three major constitutes of plasma membranes and how are membranes of eukaryotic cells organized? - answer--cholesterol, integral membrane protein, phospholipids. Cells are enclosed by a semipermeable membrane. The membrane serves as a barrier and regulates cell size and function. Membranes also surround intracellular structures (ex. mito, lysosomes). Within the cell (cytosol): ions, proteins, water, and many organelles. 2. There are several types of proteins in the plasma me...

Cell Theory - Every living thing is made up of cells Basic Tenent of biology Prokaryotes - Cells with no nucleus lack internal cellular bodies called organelles do not divide by mitosis included= bacteria Eukaryotes - Have nucleus Have organelles divide by mitosis included= plants, animals, humans cell membrane - (also known as cell membrane) lies at the border of the cells primarily made up of proteins and lipids, especially phospholipids

Atrophy Correct Answer-E. Cells decrease in size P. Still functional; imbalance between protein synthesis and degradation. Essentially there is an increase in the catabolism of intracellular organelles, reducing structural components of cell Physiologic: thymus gland in early childhood Pathological: disuse (muscle atrophy d/ decrease workload, pressure, use, blood supply, nutrition, hormonal stimulation, or nervous stimulation) Hyperplasia Correct Answer-E: cells increase in number, mitosi...
