Exam 5: How Cells Work

A new bacterial cell is found that is able to grow without food as long as sunlight is available.This cell likely uses ________ to produce its own food.

As an energy carrier,ATP differs from NADPH in that

Which of the following events in a cell would require ATP?

The illustration below indicates that photosynthesis and cellular respiration are both complementary and balanced.An excess of sugars produced fossil fuels like coal and petroleum; this suggests that in the past,

The chemical 3-(3,4-dichloro-phenyl)-1,1-dimethylurea (DCMU)blocks the movement of electrons at the point indicated by the black,downward-pointing arrow in the figure below.Which of the following would be an immediate effect of treating a chloroplast with this drug?

The three stages of cellular respiration (in order)are

Which of these molecules carries the most energy?

The step of cellular respiration that produces a product that will also be used in the Calvin cycle is the ________.

Two students are debating whether switching energy production from fossil fuels to traditional biomass would reduce carbon dioxide emissions.Explain the role of photosynthesis in storing carbon dioxide in these two energy sources.What is the total energy consumption shown for these two energy sources?

The enzyme rubisco is important to the process of

Which step of cellular respiration occurs outside the mitochondria?

Photosynthesis and cellular respiration cycle the element ________ through the environment.When a plant does photosynthesis,it takes this element from the air and produces sugars.When animals conduct cellular respiration,they break down sugars and exhale a gas that contains this element.

A plant cell is mutated so ATP synthase no longer functions.Which process will be affected?

Which of the following is a similarity between photosynthesis and respiration?

Photosynthesis and cellular respiration are both complementary and relatively balanced,but early history of life on Earth showed increasing oxygen concentrations.This indicates that

When ATP breaks down into ADP and a phosphate group,

Support or refute the following statement: "Cells would not be able to survive unless anabolic and catabolic processes occurred in linked reactions."

The energy carriers NADPH and NADH differ structurally.Functionally they are

Photosynthetic organisms capture energy from sunlight and convert it into chemical bonds by forming

A hypothetical chemical forms a permanent bond between the phosphates in ATP.How would this affect the cell?
