(HS-LS1-1) Structure and Function
This macromolecule's shape determines its function and is built from amino acids.
What is a protein?
The selectively permeable barrier surrounding the cell.
What is the cell membrane?
This process maintains stable internal conditions in an organism.
What is homeostasis?
The main energy currency of the cell.
What is ATP?
A feedback loop that reverses a change to maintain balance.
What is negative feedback?
Proteins that speed up chemical reactions in cells.
What are enzymes?
This structure is found in plant cells and helps with photosynthesis.
What is the chloroplast?
The hormone that lowers blood glucose levels.
What is insulin?
The organelle where aerobic respiration occurs.
What is the mitochondrion (mitochondria)?
The waste product released when oxygen is used in respiration.
What is carbon dioxide?
A change in temperature or pH that alters a protein's shape and function.
What is denaturation? or What is being denatured?
This process requires energy to move substances against a concentration gradient.
What is active transport?
This type of feedback amplifies a change, such as childbirth.
What is a positive feedback?
The process by which cells convert glucose into ATP using oxygen.
What is cellular respiration? or What is aerobic respiration?
The hormone that raises blood glucose levels.
Wha is glucagon?
A mutation that alters amino acid sequence can affect this property of a protein.
What is function?
This structure modifies, sorts, and packages proteins.
What is the Golgi apparatus?
The organ plays a key role in regulating blood sugar levels.
What is the pancreas?
This process occurs when oxygen is not available.
What is fermentation?
The movement of molecules from high to low concentration without energy.
What is diffusion?
The specific region of an enzyme where the substrate binds.
What is the active site?
Ribosomes are responsible for this cellular process.
What is protein synthesis?
The system responsible for coordinating feedback responses in the body using chemicals.
What is the endocrine system?
Lactic acid buildup occurs in muscles during this type of respiration.
What is anaerobic respiration?
The relationship describing how a protein's shape relates to its job.
What is structure determines function?
