the products of the light reactions of photosynthesis that are utilized in the Calvin cycle

atp and nadph

describe the functioning of photosystem II?

P680 are filled by electron derived H20

Chloroplasts are found mainly in the cells of the ______, the interior tissue of the leaf


What features are associated with photosystem I?

P680are filled by electrons derived from H2O

Which events occurs in the light reactions of photosynthesis?

solar to chemical energy. splitting of water, regeneration of atp

Where does the Calvin cycle take place?


In any ecosystem, terrestrial or aquatic, what group(s) is (are) always necessary?


When oxygen is released as a result of photosynthesis, it is a direct by-product of

splitting of water

What are the products of linear photophosphorylation?

atp and nadph

Reduction of NADP+ occurs during

light reactions of PI

Assume a thylakoid is somehow punctured so that the interior of the thylakoid is no longer separated from the stroma. This damage will have the most direct effect on which processes?

Light Reactions

In a plant cell, where are the ATP synthase complexes located

Thylacoid Membrane

Where do the enzymatic reactions of the Calvin cycle take place?


Where does glycolysis take place in eukaryotic cells?


In addition to ATP, what are the end products of glycolysis?

nadh and pyruvate

The ATP made during glycolysis is generated by

substrate level phosporlation

During glycolysis, when each molecule of glucose is catabolized to two molecules of pyruvate, most of the potential energy contained in glucose is

stored ATP in phosphate groups

In the process of carbon fixation, RuBP attaches a CO2 to produce a six-carbon molecule, which is then split to produce two molecules of 3-phosphoglycerate. After phosphorylation and reduction produces glyceraldehyde 3-phosphate (G3P), what more needs to happen to complete the Calvin cycle?

Regeneration of Co2 acceptor (RuBP)

A molecule that is phosphorylated has

increased in chemical reactivity, and can do cellular work

In glycolysis, for each molecule of glucose oxidized to pyruvate what comes from this?

4 atp - 2 used = 2atp (2nadh)

Starting with one molecule of glucose, the energy-containing products of glycolysis

2 atp, 2 nadh, 2 pyruvate

The light reactions of photosynthesis supply the Calvin cycle with

atp and nadph

Which of the following does not occur during the Calvin cycle?

realease of oxygen

Which sequences correctly represents the flow of electrons during photosynthesis

H20 -adph - calvin cycle

Reactions that require CO2 take place in

stroma, (calvin cycle)

The NADPH required for the Calvin cycle comes from

PSI, reduction of nadp+ in light reactions

What is the primary function of the Calvin cycle?

synthesis of sugar (G3p)

Why is glycolysis described as having an investment phase and a payoff phase?

spends atp, and produces atp

Which kind of metabolic poison would most directly interfere with glycolysis?

agent that mimics structures of glucose, and not metabolized

How many carbon atoms are fed into the citric acid cycle as a result of the oxidation of one molecule of pyruvate

3 ( 2 CO2 are released)

The transport of pyruvate into mitochondria depends on the proton-motive force across the inner mitochondrial membrane. How does pyruvate enter the mitochondrion?

through active transport

Why is glycolysis considered to be one of the first metabolic pathways to have evolved?

present in most organisms, no O2, found in cytosol

Which of the following normally occurs regardless of whether or not oxygen (O2) is present?


Inside an active mitochondrion, most electrons follow which pathway?

calvin cycle - nadh - electron transport chain - oxygen

Which of the following produces the most ATP when glucose (C6H12O6) is completely oxidized to carbon dioxide (CO2) and water?

oxidated phosporylation

The primary role of oxygen in cellular respiration is to

make the fall of electrons easier

During aerobic respiration, electrons travel downhill in which sequence?

glucose - nadh - electron transport chain - oxygen
