Processes of Living Organisms
The internal stability that organisms maintain
What is homeostasis?
Special proteins that affect the rate of chemical reactions.
What are enzymes?
The body's primary defense against disease-causing pathogens
What is an Immune System?
The cycle in which the output of a system "feeds back" to either modify or reinforce the action taken by the system.
What is a feedback mechanism?
The shape, conditions, temperature, and pH, can either speed up or slow down the rate of action.
What is an enzyme reaction?
Green colored molecules in plant cells.
What are chloroplasts?
A simple sugar.
What is glucose?
A rapid immune system reaction to environmental substances that are normally harmless.
What is an allergy?
A thing or event that evokes a specific functional reaction in an organ or tissue.
What is Stimuli?
Any substance that can affect the rate of a chemical reaction without itself being changed or used up during the reaction.
What is a catalyst?
The process by which chemical energy is stored in nutrients is released for use in cells.
What is respiration?
Cellular Respiration in many organisms is completed in these organelles.
What is a Mitochondria?
The result of an attack on the immune system.
What are AIDS?
A hormone that prompts glucose to move from the blood into body cells, resulting in a lower glucose level in the blood.
What is Insulin?
The measure of a substance of whether a substance is acidic,neutral, or basic.
What is pH?
The process used to generate molecules during cellular respiration.
What is ATP?
Obtaining oxygen from the environment and releasing carbon dioxide.
What is gas exchange?
Proteins that either attack the invaders or mark them for killing.
What are antibodies?
Specialized cells that surround pores on the surface of the leaf.
What are Guard Cells?
The digestion,synthesis,cellular respiration, and photosynthesis, are made possible in living things by enzymes.
What is the Biochemical Processes?
Chemical processes that occurs in living things
What is Biochemical Processes?
Acts as food reserve molecule
What are Lipids?
These molecules trigger a response from the immune system.
What are Athigens?
When the glucose level is above normal limits, an endocrine organ secretes insulin.
What is a pancreas?
Found in the human stomach and has a pH that matches the acid environment found there.
What is Pepsin?
