Substances Involved.
Definition of Oxygen
A molecule that organisms get from the air or water around them and use to release energy.
Definition of Cellular Respiration
Is the process by which cells derive energy from glucose.
Definition of Circulatory System
that system that circulates blood and lymph through the body , consisting the heart , and blood vessels.
Definition of Molecule
a group of atoms joined together in a particular way.
Definition of Energy
The strength and vitality required for sustained physical of mental activities
Definition of Carbon Dioxide
Is a clear gas composed of one atom of carbon (C) and two atoms of oxygen (O)
Definition of Metabolism
The chemical processes that occur within a living organism in order to maintain life.
Definition of Digestive System
The organs that take in food and liquid and break either down into substances that the body can use for energy.
*Explain the relationship between glucose, oxygen, and cellular respiration.
Cellular respiration uses glucose and oxygen to produce energy. Glucose is broken down, releasing stored energy. Oxygen acts as the final electron acceptor in this process. This energy is then stored as ATP, powering cellular functions.
Definition of Evidence
The available body of facts or information indicating whether a belief or proposition is true and valid.
Definition of Glucose
A simple sugar which is an important energy source in living organisms and is a component of many carbohydrate.
Definition of Chemical Reaction
A process that involves rearrangement of a molecular or ionic structure of a substance.
Definition of Respiratory System
the body system that takes in oxygen and releases carbon dioxide
*What is the difference between a chemical reaction and metabolism in the body?
A chemical reaction is a single, specific transformation of reactants into products. Metabolism encompasses all the chemical reactions within an organism, including synthesis (anabolism) and breakdown (catabolism) of molecules.
Definition of Reasoning
the action of thinking about something in a logical, sensible way.
Definition of Proteins
A category of large molecules that perform important functions inside living things
Definition of System
a set of interacting parts forming a complex whole
*Why is the circulatory system important for maintaining homeostasis in the body?
The circulatory system transports essential substances like oxygen and nutrients to cells while removing waste products like carbon dioxide. This maintains stable internal conditions (homeostasis) throughout the body.
Definition of Claim
state or assert that something is the case, typically without providing evidence or proof.
Definition of Starch
a type of energy storage Molecules made of many glucose Molecules connected together.
*How do the digestive and circulatory systems work together to provide energy to cells?
The digestive system breaks down food into absorbable nutrients, primarily glucose. The circulatory system then transports this glucose to cells throughout the body, where it's used in cellular respiration to produce energy.
*Describe how starch is related to glucose and how both play a role in energy storage.
Plants store glucose as starch (long-term energy). Animals use glycogen:the stored form of glucose that's made up of many connected glucose molecules (short-term). Both are glucose polysaccharides: a carbohydrate (e.g. starch, cellulose, or glycogen) whose molecules consist of a number of sugar molecules bonded together.
