ATP & Photosynthesis Quiz

Sea grasses grow on the ocean floor in shallow areas.  Runoff from the land into the ocean can cause the waters to become cloudy.  Cloudy water affects the sea grasses’ ability to make their own food  because there is not enough

• ATP

• light

• Carbon dioxide

• water

Two potted plants were used in an experiment to study the amount of starch formed in leaves under different conditions. The table describes the conditions the plants were subjected to and the results of testing the leaves with potassium iodide to detect the presence of starch.

Which of these conclusions is BEST validated, based on the experimental data?

• Carbon dioxide is essential for photosynthesis.

• Starch is not produced during photosynthesis.

• Oxygen is not produced during photosynthesis.

• Sunlight is essential for photosynthesis.

What chemical from the atmosphere is used in the Light Independent/Calvin Cycle to produce sugars?

• CO2

• O2

• H2O

• C6H12O6

The manufacture of __________ is the ultimate goal of photosynthesis.

• lipids

• nucleic acids

• proteins

• carbohydrates

The ultimate source of energy for all living things on Earth is

• Carbohydrates

• Water

• Oxygen

• Sun

Andy observed the gas production of a water plant going through photosynthesis. The bubbles being formed in the test tube must be

• CO2

• H2O

• O2

• glucose

Which of the following chemical equations summarizes photosynthesis?

• 6CO2 + 12H2O --> C6H12O6

• 6H2O + 6 CO2 --> C6H12O6 + 6O2

• C6H12O6 + 6O2 --> 6CO2

• 6O2 + 6CO2 + H2O --> 6H2O + 12CO2 + 2C12H2

Leaves fall off of deciduous trees in SC in autumn.  This reduces the amount of photosynthesis possible for that tree.  This reduced amount of photosynthesis is caused in part by which of the following:

• amount of water increases

• light intensity + temperature are reduce

• amount of carbon dioxide reduced

• the sugar freezes in the leaf

What are the products of photosynthesis?

• Energy and Oxygen

• Glucose and Oxygen

• Carbon Dioxide and Water

• Glucose and Carbon Dioxide

A mitochondrion is to aerobic respiration as a chloroplast is to

• Fermentation

• Glycolysis

• Photosynthesis

• Respiration
