Bio 100L Study Guide 5 (1)

Products of Respiration

Carbon dioxide, water, and energy (ATP)

Reactants of Photosynthesis

Carbon dioxide, water, and sunlight (energy)

Cellulose

A complex carbohydrate present in wood.

Combustion Product of Wood and Respiration of Carbohydrates

Carbon dioxide (CO2)

Photosynthesis Equation

6CO2 + 6H2O + light energy → C6H12O6 + 6O2

Effect of Phenol Red on Water

Phenol red changes color in response to pH levels.

Result of Breathing into Water with Phenol Red

The water became more acidic, causing a color change due to increased CO2.

Outcome of Elodea Stems in Solution from Breathing Experiment

The solution became less acidic (more basic) due to photosynthesis.

Purpose of Adding Sodium Azide

To inhibit cellular respiration.

Greenhouse Gas related to Global Warming

Carbon dioxide (CO2) is related to both photosynthesis and cellular respiration.

Optimum Fuel for Yeast according to Experiment

Sucrose (highest gas production of 2.2 mm)

Order of Effectiveness of Respiratory Fuels in Yeast

1. Sucrose, 2. Protein, 3. Glycerol.

Four Substances Necessary for Plant Growth

Water, sunlight, carbon dioxide, and nutrients.

Anaerobic Respiration End Product in Humans

Lactic acid.

Anaerobic Respiration End Product in Yeast Cells

Ethanol and carbon dioxide.

ATP Generation in Anaerobic vs. Aerobic Respiration

Aerobic respiration generates more ATP than anaerobic respiration.

Most Abundant Greenhouse Gases

Carbon dioxide (CO2) and methane (CH4), with carbon dioxide being the most abundant.
