According to the data provided, within THIS temperature range shown here, which appears to have a more limiting effect on the rate of photosynthesis - light or temperature? EXPLAIN your answer using data/trends from the graph to justify your answer. - 4 pts

Oxygen gas is produced when G3P molecules are combined to make other organic molecules.

Which of the following statements best explains how the energy in a photon of light is stored in a molecule of the sugar G3P?

Light energy energizes electrons to make ATP and NADPH, which provide energy to produce G3P in the Calvin cycle.

Light energy directly provides energy to ATP synthase, which produces ATP during the light reactions.

Light energy directly provides energy to RuBP and CO2, which produce G3P in the Calvin cycle.

What is the primary function of the Calvin cycle?

An early step in the process of carbon fixation combines three molecules of CO2 with three molecules of RuBP to produce three 6-carbon molecules, which are immediately converted to six 3-carbon molecules.

release of two G3P to make sugars and regeneration of ATP from ADP

release of one G3P to make sugars and regeneration of RuBP

release of one G3P to make sugars and regeneration of citrate

release of one G3P to make sugars and regeneration of NADPH from NADP+

Above is an image of a thylakoid. A and C are the photosystems, as shown by the green pigments on their surface. E is where hydrogen ions DIFFUSE down their gradient. E is therefore the

NADP reductase

Rubisco

ATP synthase

Electon Transport Chain

When NADPH becomes NADP+, the energy released is provided to the molecules of the Calvin Cycle to power the reactions there. It would be most appropriate to say that

NADP+ got reduced at the Calvin Cycle

NADP+ got oxidized at the Calvin Cycle

NADPH got oxidized at the Calvin Cycle

NADPH got reduced at the Calvin Ccyle

What accurately describes the flow of the H+ from water?

water --> photosystem II --> photosystem I --> NADPH

water --> Calvin cycle --> photosystem II --> ATP synthase

water --> photosystem I --> photosystem II --> NADPH

water --> photosystem I --> NADPH --> photosystem II --> G3P

Which part would be considered a female part of the flower? Choose all that apply

In which part of the flower would you find a male gamete? Give the most specific answer.

Which part of the flower would eventually become a fruit?

The oxygen atoms that end up in G3P or other glucose derivitives came from which molecule?

CO2

H2O

RuBP

NADPH

Which statements best describes why plants perform both cyclic and noncyclic photophosporylation

The plant can choose which set of reactions to follow, based on environmental conditions like wind or drought.

Different types of plants perform the different reactions - some plants would perform cyclic, while others have evolved to perfom non-cyclic reactions.

Extra ATP is needed, above the amounts created by non-cyclic light dependent reactions

Extra NADPH is needed, above the amounts creatd by the non-cyclic light dependent reactions

In the vascular bundle of a plant you would find specialized cells for water transport and specialized __ cells for sugar transport.

Photosynthesizes have evolved to have more than one type of pigment molecule. Why was this an advantage for?

It was not an advantage, it happened accidentally and does not provide an advantage.

Since pigment molecules are broken down to harness their potential energy for the dark reactions of photosynthesis, the more pigment molecules the plant has the more sugar it can make.

Having accessory pigments increases the range of wavelengths and thus energy a plant can get from the suns’ radiation.

Chlorophyll is a very weak molecule that only absorbs green wavelengths, so plants require accessory pigments otherwise they would not be able to create enough food to survive.

This is a false statement, each type of organisms has one type of pigment molecule.
