• Water, oxygen, and light are inputs while carbon dioxide and glucose are outputs

• Water, oxygen, carbon dioxide, and light are inputs and glucose is the output

• Water, carbon dioxide, and light are inputs while oxygen and glucose are outputs

• Glucose, oxygen, and light are inputs while carbon dioxide and water are outputs

Multiple Choice

Which of the following is NOT a necessary input for the process of photosynthesis?

• CO₂ (carbon dioxide)

• Sunlight

• H₂O (water)

• O₂ (oxygen)

Multiple Choice

Where within the cell does photosynthesis take place?

• cytoplasm

• chloroplasts

• mitochondria

• nucleus

Multiple Choice

Which item listed is NOT produced in the process of cellular respiration?

• CO₂ (carbon dioxide)

• C₆H₁₂O₆ (glucose)

• H₂O (water)

• Energy in the form of ATP

Multiple Choice

Where within the cell does the process of respiration take place?

• Inside the mitochondria

• Outside of the mitochondria

• Both inside and outside the mitochondria

• chloroplasts

Multiple Choice

How many ATP molecules are required to fuel glycolysis?

• 1

• 2

• 3

• 4

Multiple Choice

The role of ATP synthase is to

• onvert NADH into NAD+

• convert FADH into FAD

• convert ADP into ATP

• convert ADP into NADH

Multiple Choice

The Krebs cycle is also known as the citric acid cycle because

• citric acid is the 1st compound formed in the cycle

• cycle begins with the entry of citric acid

• citric acid the final product

• citric acid is the compound coverted to ATP

Multiple Choice

In the Krebs cycle,

• ATP is broken down into ADP & AMP

• CO₂ is converted into pyruvic acid

• pyruvic acid is broken down, releasing CO₂ & energy

• pyruvic acid is broken down into ATP

Multiple Choice

Why is it that your body temperature remains stable at 37° Celsius even after vigorous exercise?

• Cell respiration uses 100% total energy of glucose

• Cell respiration uses 36% energy, the rest is stored as glucose

• Cell respiration uses 64% total energy, thre rest is stored as glucose

• Cell respiration uses 36% energy, the rest is released s heat
