Exam 4: How Cells Work

For each characteristic below, state if it applies to photosynthesis and/or cellular respiration. a.photosynthesis only b.cellular respiration only c.both photosynthesis and cellular respiration d.neither photosynthesis nor cellular respiration -used by animal cells

A mutation in a plant cell produces rubisco enzymes, which can only bind O₂ (and not CO₂). What would be the outcome of this mutation?

Which of these carries the most energy?

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

In many organelles, groups of different enzymes are located on membranes in close proximity to each other because

Humans store sugars in the form of glycogen. Glycogen is made by linking many glucose molecules together. This process is ________.

For each characteristic below, state if it applies to photosynthesis and/or cellular respiration. a.photosynthesis only b.cellular respiration only c.both photosynthesis and cellular respiration d.neither photosynthesis nor cellular respiration -produces sugars

Plants and animals use different energy storage molecules, yet they both use the same mechanism to "burn" their stored energy. How can plants and animals both be successful, even though they "burn" different energy storage molecules?

The three stages of cellular respiration (in order) are

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

A chemical reaction that uses ATP to build cellular components is

What is the role of water in photosynthesis?

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

Some kinds of drain cleaners use enzymes rather than strong, more dangerous chemicals. These enzymes must be able to

A cell is found that is able to use sunlight to produce ATP, but it does not produce NADPH. The portion of the light reaction that is not functioning is ________.

Enzymes can catalyze a reaction only if

The energy carriers NADPH and NADH differ structurally. Functionally they

Examine the illustration below. Which statement best summarizes the contribution of Photosystem I (PSI) during photosynthesis?

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

In a human cell,
