U2L5 You Are What You Eat Flashcards
what is cellular respiration?
the process of taking the energy stored in the chemical bonds of sugar and oxygen and converting it to useable energy
what is glucose?
a simple 6-carbon energy
what is photosynthesis?
the process of changing light energy into stored chemical energy in the form of sugars
when is chemical reactions?
a chemical reaction occurs when the chemical structure of a substance changes.
true or false.
during chemical reactions matter is not created or destroyed; it can simply change forms.
true
what is the conservation of matter?
during chemical reactions matter is not created or destroyed; it can simply change forms
what is cellulose?
a carbohydrate made from glucose molecules
what does in cellulose do in cells?
the cellulose in cell walls gives the plants structure ad helps the plants stay upright
how is the conservation of matter shown when a cow eat grass?
a cow receives the glucose it needs by eating grass and other plants. the cow’s digestive system performs many chemical reactions that break down the plants into smaller molecules. the cow then uses these molecules to create new biomolecules that grow new cells, repair body tissues, and perform other cell functions.
what is cellular respiration?
a series of chemical reactions that uses glucose and oxygen to make ATP
what is ATP?
an energy molecule that can be used by the cells for life processes
why isn’t glucose used for energy?
glucose has energy stored within its bonds, but the cells cannot use this energy directly
why are organisms what they eat?
due to the laws of conservation of matter, all atoms that enter a chemical reaction will be used to make the substances formed during the chemical reaction.
what does the integumentary system and why does it need cellular respiration?
it grows new tissue to replace the damaged skin. this process requires a lot of energy. this energy is produced when glucose and oxygen are used to make ATP during cellular respiration.
give four examples of processes that would require ATP during wound healing.
- the formation of new body cells
- the creation of protiens needed for wound-healing fuction
- cell division to create new boby cells
- immune system actions
