Metabolism Flashcards
Understand how our body systems work together to provide body cells with the molecules that they need.
A functioning human body has molecules from _______ and ___ in its cells.
food and air
Cells can only use molecules that are _____ enough to enter a cell.
small
The _________ system brings in oxygen molecules from the air.
respiratory
The ________ system brings in food and breaks it down into smaller molecules.
digestive
The ________ system transports glucose, oxygen, and amino acid molecules to cells in the body.
circulatory
A problem with a body ____ can result in less oxygen, glucose, or amino acids getting to cells.
systems
In order to release ______, cells need both glucose and oxygen molecules.
energy
Inside cells, glucose and oxygen change into different molecules. This is called ____ _____.
cellular respiration
Cells grow and repair themselves with _______ molecules.
protein
Molecules that are the building blocks of proteins
amino acids
A molecule made of carbon and oxygen atoms and is released by the respiratory system.
carbon dioxide
The chemical reaction between oxygen and glucose that releases energy into cells
cellular respiration
A process in which atoms rearrange to form new substances
chemical reaction
The body system that transports molecules to and from all cells of the body
circulatory
The body system that takes in food and breaks it down
digestive
The ability to make things move or change
energy
Molecule that living things use to release energy and is made of carbon, hydrogen, and oxygen.
glucose
The body’s use of molecules for energy and growth
metabolism
A group of atoms joined together in a particular way
molecule
A molecule that organisms get from the air or water around them and use to release energy
oxygen
The body system that takes in oxygen and release carbon dioxide
respiratory system
A type of energy storage molecule made of many glucose molecules connected together
starch
A category of large molecules that are made up of many amino acids
protein
A set of interacting parts forming a complex whole
system
