The study of plant physiology
The study of psychological disorders
What are the two main types of body cells?
Muscle and nerve cells
Epithelial and mesenchymal cells
Blood and bone cells
Epithelial and connective cells
What is the main function of mitochondria in a cell?
Energy production through oxidative phosphorylation
Carbohydrate synthesis
Lipid breakdown
Protein synthesis
What is the term used to describe the increase in cell size and consequently organ size?
Hyperplasia
Metaplasia
Atrophy
Hypertrophy
What is the main consequence of increased cytosolic calcium in a cell?
Enhanced cell growth
Increased protein synthesis
Disruption of membrane and cytoskeletal proteins
Decreased ATP production
What is the primary cause of cell injury due to toxins and UV radiations?
Free radicals
Plasma membrane defects

Mitochondrial damage
What is the role of ATP in cellular processes?
Maintaining cell osmolarity
Transport processes
Protein synthesis
All of the above
What is the definition of free radicals in cells?
Stable, non-reactive chemical species
Inactive molecules with no role in cell function
Highly reactive species with paired electrons
Unstable, highly reactive species with unpaired electrons
What is the difference between hypoxia and ischemia?
Hypoxia refers to lack of blood flow, while ischemia refers to lack of oxygen
Hypoxia refers to lack of oxygen, while ischemia refers to lack of blood flow
Hypoxia affects the whole body, while ischemia affects a region of the body
Hypoxia is caused by blood vessel problems, while ischemia is caused by environmental factors
What is the main consequence of defects in plasma membrane permeability in a cell?
Increased ATP production
Enhanced cell growth
Release of cytochrome C into cytoplasm leading to cell death
Improved protein synthesis
What is the process by which cells change from one type to another?
Hyperplasia
Dysplasia
Atrophy
Metaplasia
What is the term used to describe the disorderly overgrowth of cells that is pre-malignant?
Hyperplasia
Atrophy
Metaplasia
Dysplasia
