Homeostasis & Metabolism
This term refers to an organism’s ability to maintain a stable internal environment.
What is Homeostasis?
What is Carbon?
The control center of the cell, containing the DNA.
What is the nucleus?
The movement of molecules from high concentration to low concentration without using energy is called ____.
What is Diffusion?
This body system breaks down food into nutrients for absorption.
What is the Digestive system?
The consequence if an organism fails to maintain homeostasis
What is sickness or death?
The building blocks (basic units) of carbohydrates, such as starch.
What is Glucose?
This organelle is the site of cellular respiration and produces ATP energy (“powerhouse” of the cell).
What is Mitochondria?
Moving molecules from low concentration to high concentration (against the gradient) using energy is called ____.
What is Active transport?
This body system transports oxygen and nutrients throughout the body.
What is the Circulatory system?
Define: Metabolism. (What does an organism’s metabolism encompass?)
What is the sum of all chemical reactions occurring within an organism’s cells (all life processes together)?
Amino acids are the building blocks of this type of organic compounds.
What are Proteins?
Organelle found only in plant cells is the site of photosynthesis.
What is Chloroplast?
A cell membrane that allows only certain substances to pass through is described as _________________.
What is Selectively permeable?
This body system exchanges gases (O₂ in, CO₂ out) in the body.
What is the respiratory system?
Give an example of a homeostatic response in the human body. (E.g., how does the body respond to overheating?)
For example, when body temperature rises, the body sweats to cool down – a homeostatic response to maintain normal temperature
Lipids (fats and oils) are composed of these two types of smaller subunits.
What are Fatty acids and glycerol?
This organelle stores water and waste (large in plant cells, small in animal cells).
What is Vacuole?
Term: Osmosis – What specific type of diffusion does this refer to?
What is Osmosis – the diffusion of water through a membrane?
This body system removes metabolic waste products from the blood and the body.
What is the Excretory system?
The term dynamic equilibrium is often used to describe the body’s internal balance. This steady-state condition is also known as
What is Homeostasis?
Nucleotides (phosphate + sugar + base) are the basic units of this organic molecule that stores genetic information.
What are Nucleic acids? (DNA and RNA are made of nucleotide units).
This tiny organelle, often represented as a dot, is the site of protein synthesis in cells.
What is the ribosome?
What happens to an animal cell placed in a very salty (high concentration) solution? (Describe the water movement and effect on the cell.)
It will shrivel and shrink as water diffuses out of the cell (in a hypertonic/salty solution, water leaves the cell).
Two systems control and coordinate body functions: the fast-acting nervous system and the slower-acting __________ system (uses hormones).
What is Endocrine system?
