Ch. 2 Cell Processes and Energy

What are the products of photosynthesis?

• carbon dioxide and water

• oxygen and water

• carbon dioxide and sugars

• oxygen and sugars

What happens during photosynthesis?

• The cell uses oxygen to make food

• The cell uses the energy in sunlight to make food

• The cell uses glucose to make oxygen

• The cell uses the energy in sunlight to make carbon dioxide

Under which of the following conditions is lactic-acid fermentation most likely to occur?

• a sprint at the end of a race

• a long slow walk

• sleeping

• playing video games

What captures energy from sunlight during photosynthesis?

• solar cells

• stomata

• chlorophyll

• carbohydrates

Which of the following equations best represents photosynthesis?

• C + O2 + H2O = CO2 + HOH

• 6CO2 + 6H2O = C6H12O6 + 6O2

• 6C + 6H2O = C6H12O6

• C6H12O6 = 6CO2 + 6H2O

The stage of respiration that releases most of the energy in glucose occurs in the _____.

• nucleus

• chloroplast

• cytoplasm

• mitochondria

The energy-releasing process that does not require oxygen is called

• photosynthesis

• respiration

• fertilization

• fermentation

The job of the chloroplast is

• to make proteins for all cell processes

• to make glucose through the process of photosynthesis

• to make ATP through the process of cellular respiration

• to break down waste for the cell

Step 1 of cellular respiration takes place in a cell's

• nucleus

• mitochondria

• cytoplasm

• vesicle

Why is cellular respiration necessary for most organisms?

• to turn glucose into useable energy for cells

• to breathe

• to create oxgen

• to get rid of waste
