Lab Bio Ch. 5 Mini-Test 1 Quizs

Stacks of thylakoid membranes in the chloroplasts are called:

• stroma

• stomata

• granum

• chlorophyll

The main source of chemical E used by cells is:

• DNA

• ADP

• ATP

• NADH₂

These are found in the chloroplasts. They are light absorbing molecules:

• stomata

• proteins

• pigments

• stroma

What organelle performs photosynthesis?

• chloroplast

• mitochondria

• nucleus

• cytoplasm

What is the purpose of the Calvin Cycle?

• to use light to make glucose (sugar)

• to use carbon dioxide to make chemical E (ATP and NADPH)

• to use chemical E (ATP and NADPH) to turn carbon dioxide into glucose (sugar)

• to turn light E into chemical E (ATP and NADPH)

We know that glucose is C₆H₁₂O₆. The Cs and the Os come from the CO₂. Where do the Hs come from?

• light E

• water

• protons

• the stroma

The process of breaking down materials (such as food) in order to make E:

• glycolysis

• metabolism

• homeostasis

• photosynthesis

Temperature can influence the rate of photosynthesis in a plant because _______ inside can denature (not work properly) if it becomes too hot/cold.

• thylakoids

• ATP

• reactants

• enzymes

True or False: ATP is a reusable molecule.

• True

• False

What is the purpose of the Light Dependent Reactions?

• to use light to make glucose (sugar)

• to use light to turn water into carbon dioxide

• to use chemical E (ATP and NADPH) to turn carbon dioxide into glucose (sugar)

• to turn light E into chemical E (ATP and NADPH)
