105E.1 Building Blocks of the Human Body
The process of building up larger molecules from smaller ones is:
Anabolism
example of metabolism?
Building up larger molecules from smaller ones, releasing energy to perform specific body functions and breaking down of larger molecules or substances into smaller ones are examples of metabolism.
The release of energy within a cell necessary for the performance of specific body functions is caused by:
Catabolism
T/F The process of cell growth and division is called the growth cycle.
False
What is another name for histology?
Microscopic anatomy
Organelles in the cytoplasm that take in nutrients, break them down and create ATP energy molecules for the cells is called:
Mitochondria
The tissue that contracts, when stimulated, to produce motion is known as:
Muscular tissue
Which type of tissue coordinates body functions in addition to carrying messages to and from the brain and spinal cord?
Nerve tissue
All of the following statements about mitochondria are correct except

The colorless, gel-like substance containing water, salt and nutrients that cells are composed of is referred to as:
Protoplasm
T/F Carbohydrates are converted to glucose for energy in the body, and excess carbohydrates can result in excess body fat.
True

mitosis
What is the function of the muscular system?
move the body.
The body system that sends and receives body messages is called the:
nervous system.
The control center of cell activities is called the:
nucleus
What three basic parts are found in most human cells?
nucleus, cytoplasm and cell membrane
A separate body structure made up of tissue that performs a specific function as part of a system is a(n):
