Question

fill in the blank
lucille’s cells need ____v__ and __w__ in order for her body to function properly. if lucille’s x system is not working properly, then there wouldn’t be enough oxygen molecules passing through her respiratory system, which means there wouldn’t be enough oxygen sent to her cells through her y system. if lucille’s circulatory system is not working properly, then there would not be enough oxygen molecules being delivered to her cells. it’s hard for her to play soccer because if her cells aren’t getting enough oxygen, then her cells can’t release enough z__ from the chemical reaction with glucose called cellular respiration. therefore, she might not have enough energy to play.

select the correct word for blank \v\ *
○ amino acid
○ energy
○ glucose
○ starch

select the correct word for blank \w\ *
○ amino acid
○ oxygen
○ starch
○ protein

Explanation:

For Blank "V"

Cells need glucose (a simple sugar) and oxygen for cellular respiration to produce energy. Amino acid is for protein synthesis, energy is the product, starch is a complex carbohydrate (not directly used by cells). So glucose fits for V.

Cells require oxygen (along with glucose) for cellular respiration. Amino acid, starch, and protein don't fit the cellular respiration reactant role here. Oxygen is needed for the process.

Answer:

C. glucose

For Blank "W"
