Exam 8: Photosynthesis

Based on a variety of experiments, it is known that the rate of photosynthesis is highest when wavelengths of light between 400 and 500 nm are used, and when wavelengths around 700 nm are used.What does this indicate about the relative importance of chlorophyll a and b in photosynthesis?

Chlorophyll b absorbs green wavelengths of light that chlorophyll a cannot absorb.In this respect, chlorophyll b acts as

If a plant's stomata were always closed, how would this affect the plant's ability to make glucose?

Which plants utilize a specialized carbon fixation enzyme and a unique cell structure to reduce the problems of photorespiration?

The ATP generated from cellular respiration is not sufficient to drive the Calvin cycle in plants, even if appropriate levels of NADPH and CO2 are present.Why not?

Most plants incorporate carbon dioxide into sugars by means of a cycle of reactions called the

Which type of plant can utilize the Calvin cycle?

Fall leaf color on deciduous trees is a result of

Light-dependent reactions generate

One of the disadvantages of the C₄ pathway is that it requires

In photosynthesis, ATP is made by

You are working on a research project that involves a mutational analysis of the light harvesting complex Lhca1, which is an important light harvesting complex found in plants.Your labmate asks where this complex is located.You say it is in the.

The Calvin cycle of a plant exposed to light during the day that is suddenly put in the dark

The splitting of water and the generation of oxygen occur where?

The role of the antenna complex in a photosystem is to

Plants that show a pattern of stomatal opening and closing that is the reverse of C₃ plants are called

The plant hormone abscisic acid (ABA) is involved in the regulation of photorespiration.Based on this information, ABA likely plays a role in

Since Rubisco can either fix carbon or oxidize RuBP, what condition will be most favorable for glucose production?

During the light-dependent reactions, due to electron transport, the thylakoid space becomes

If you exposed a C₄ plant to ¹⁴CO₂ in the light, which would be the first organic molecule labeled with ¹⁴C?
