Question

1. two soccer teams, the bears and the panthers, played games at the same time in two different locations. the bears game was played at sea level, where there is a normal amount of oxygen. before their game, the players on the bears ate a lunch of mostly starch. the panthers game was played at very high altitude, where there is less oxygen. the players on the panthers ate a lunch of starch and protein. which team probably did better in their game? the bears probably did better because their cells released energy from oxygen reacting with glucose, which was broken down from starch in the digestive system. the panthers probably did better because their cells released energy from breaking down protein in the digestive system, which then combined with oxygen in cells the teams did equally well because their digestive systems just need to break down starch into glucose for cells to release energy the teams did equally well because glucose from starch can react with oxygen or proteins to release energy

Explanation:

1. Analyze the Bears' situation: They played at sea level (normal oxygen) and ate mostly starch. Starch is broken down into glucose, and cells release energy through cellular respiration (glucose + oxygen → energy, CO₂, H₂O). With normal oxygen, this process can occur efficiently.
2. Analyze the Panthers' situation: They played at high altitude (low oxygen) and ate starch and protein. Protein breakdown for energy is less efficient and not the primary energy source; also, low oxygen limits aerobic respiration.
3. Evaluate the options:

• Option 1: Correct. Bears had normal oxygen and starch (source of glucose for efficient energy release via aerobic respiration).
• Option 2: Incorrect. Protein is not the primary energy source, and high altitude (low O₂) hinders energy release.
• Option 3: Incorrect. Panthers’ low oxygen and protein - based energy (less efficient) mean they won't do as well as Bears.
• Option 4: Incorrect. Glucose reacts with oxygen (aerobic), protein breakdown is less efficient, and Panthers have low oxygen.

Answer:

The Bears probably did better because their cells released energy from oxygen reacting with glucose, which was broken down from starch in the digestive system.
