A runner has depleted all the oxygen available for muscle energy. Which of the following will facilitate his continued muscle performance? Answer: Anaerobic glycolysis What causes the rapid change in the resting membrane potential that initiates an action potential? Answer: Sodium gates open, and...

Glycoproteins surface markers called antigens, they identify cells as a part of the individuals own tissues Cell membrane Phospholipid bilayer with proteins and cholesterol Sodium-Potassium pump The plasma membrane is more soluble to potassium and less soluble to sodium. This makes it easier t...

Which component of the cell produces hydrogen peroxide (H2O2) by using oxygen to remove hydrogen atoms from specific substrates in an oxidative reaction? A) lysosomes B) peroxisomes C) ribosomes D) oxyhydrosomes Ans: B- peroxisomes What is a consequence of plasma membrane damage to the mito...

Passive transport requires energy to move an uncharged molecule across a semipermeable membrane. True False The answer is False "In passive transport, water and small, electrically uncharged molecules move easily through pores in the plasma membrane's lipid bilayer. Molecules will easily flow...

Melanin a dark brown to black pigment occurring in the hair, skin, and iris of the eye in people and animals. It is responsible for tanning of skin exposed to sunlight. Hyperventilation Alveolar ventilation that exceeds metabolic demand. The lungs remove CO2 at a higher rate than it is produced b...

T/F: Non-dividing cells, such as myocardial fibers, are capable of hypertrophy, but not hyperplasia. True T/F: Dysplasia is a common type of normal cellular adaptation. False T/F: Hypertrophy and hyperplasia rarely occur together. False T/F: A man with a history of smoking has a bronchial b...

*Chapter 1: Introduction to Pathophysiology* Risk Factor that when present increases the chance of disease Not stressors, but conditions or situations that increase the likelihood of encountering a stressor Prevalence A measure of disease that allows us to determine a person's likelihood o...

What are the properties of a eukaryotic cell • Well define nucleus. • cells are larger and have more extensive intracellular anatomy and organization than do prokaryotes. • cells bind with deoxyribonucleic acid (DNA) and are involved in the super coiling of DNA. • cells have several chr...
