Question

1. which of the following is the correct chemical formula for cellular respiration? a. 6o₂ + 6h₂o + atp → c₆h₁₂o₆ + 6co₂ b. 6co₂ + 6h₂o + atp → c₆h₁₂o₆ + 6o₂ c. c₆h₁₂o₆ + 6co₂ → 6o₂ + 6h₂o + atp d. c₆h₁₂o₆ + 6o₂ → 6co₂ + 6h₂o + atp 21. which of the following is the correct chemical formula for photosynthesis? a. 6o₂ + 6h₂o $xrightarrow{light}$ c₆h₁₂o₆ + 6co₂ b. 6co₂ + 6h₂o $xrightarrow{light}$ c₆h₁₂o₆ + 6o₂ c. c₆h₁₂o₆ + 6co₂ $xrightarrow{light}$ 6o₂ + 6h₂o d. c₆h₁₂o₆ + 6o₂ $xrightarrow{light}$ 6co₂ + 6h₂o 22. which cells in the human body would have multiple mitochondria? a. muscle b. skin c. cheek d. lung 23. which of the following is required for cellular respiration? a. carbon dioxide b. water c. sugar d. chlorophyll 24. when atp is produced in cellular respiration, some of the energy from glucose is lost as. a. heat. b. carbon. c. matter. d. light. 25. some animals can undergo photosynthesis. a. true b. false

Explanation:

• For question 20, cellular respiration is the process of breaking down glucose in the presence of oxygen to produce carbon - dioxide, water, and ATP. The correct formula is $C_6H_{12}O_6 + 6O_2

ightarrow6CO_2 + 6H_2O+ATP$.

• For question 21, photosynthesis is the process by which plants use carbon - dioxide and water in the presence of light to produce glucose and oxygen. The correct formula is $6CO_2 + 6H_2O\xrightarrow{Light}C_6H_{12}O_6 + 6O_2$.
• For question 22, muscle cells require a large amount of energy for movement, so they have multiple mitochondria to produce ATP.
• For question 23, cellular respiration requires sugar (glucose) as the fuel source.
• For question 24, when ATP is produced in cellular respiration, some of the energy from glucose is lost as heat due to inefficiencies in the energy - conversion process.
• For question 25, photosynthesis is mainly carried out by plants, algae, and some bacteria. Most animals cannot perform photosynthesis.

Answer:

1. D. $C_6H_{12}O_6 + 6O_2
