□ b glucose
□ c carbon dioxide
□ d water
question 9 (1 point)
what type of cells perform cellular respiration?
o a all cells (plants, animals, fungi, protists, bacteria)
o b only bacterial cells
o c only animal cells
o d only plant cells
question 10 (1 point)
which step of cellular respiration breaks down carbohydrates (c₆h₁₂o₆)?
o a glycolysis
o b krebss cycle
o c electron transport chain

Explanation:

• For the first question: Cellular respiration is \(C_6H_{12}O_6+6O_2

ightarrow6CO_2 + 6H_2O+ATP\). ATP is the energy - rich molecule produced (not waste). Glucose is the reactant. Carbon dioxide (\(CO_2\)) and water (\(H_2O\)) are by - products (wastes in the context of the cell's energy - producing goal).

• For the second question: All living cells (plants, animals, fungi, protists, bacteria) need to produce energy (ATP) through cellular respiration to carry out their metabolic functions.
• For the third question: Glycolysis is the first step of cellular respiration where glucose (\(C_6H_{12}O_6\)) is broken down into two pyruvate molecules. The Krebs cycle further oxidizes pyruvate - derived molecules, and the electron transport chain is mainly for ATP synthesis using the energy from electron transfer.

Answer:

• First question: C. Carbon dioxide, D. Water
• Second question: A. All cells (plants, animals, fungi, protists, bacteria)
• Third question: A. Glycolysis
