Question

A) what is the relationship between photosynthesis and cell respiration?
1. photosynthesis removes carbon dioxide from the atmosphere and cellular respiration puts it back.
2. photosynthesis releases oxygen into the admosphere, and cellular respiration uses that oxygen to release energy from food.

B) what color found in many plants is produced by which pigment?

C)what color of light are green plants the best at reflecting?
1. yellow
2. green
3. blue.
4 red

D) what are the two main sets of reactions in photosynthesis?
1. light dependent reactions and calvin cycle reactions.
2. tylakoids and grana
3. nadph producing photosystem and water splitting photosystem
4. chlorophyll and carotenoid pigments.

E) Organisms that are able to do photosynthesis are called?

1. hetrotrophs.
2. chemotrophs.
3. autotrophs

F) where is ATP actually made during the process of photosynthesis?

1. by photosystem I
2. in the calvin cycle
3. at or by an enzyme in the thylakoid membrane
4. in an electron.

G) what would be the Effect of a substance that make the THYLAKOID membrane totally...........and openly permeable to H+?
1. more sugar is made.
2. less NADP + is reduced
3. less oxygen is released
4. less ATP is made

ChlorophyII pigments aborb what wavelengths?
1. wavelenghts corresponding to green light.
2. wavelenght corresponding to red and blue light
3. wavelenghts smaller than the visible spectrum
4. wavelenghts larger than the visible spectrum.

Ribulose 1,5 -bisphosphate also called rubico is used by plants to do what?

Answer 1

A) The correct answer is 2. Photosynthesis releases oxygen into the atmosphere, and cellular respiration uses that oxygen to release energy from food.

Photosynthesis is the process by which plants make food. The input is water , CO2 and sunlight an output is O2 and glucose.

In cellular respiration oxygen released from photosynthesis is used to breakdown glucose to release energy.

B) Chlorophyll is the pigment responsible for green color of plants.

Carotenoids is the pigment responsible for red,orange or yellow color.

   Anthocyanins are responsible for color of flower . The petal color ranges from red to blue.

Betalains are responsible for red or yellow color.

C) The correct answer is 2. Green

Chlorophyll is the pigment in green plants which absorbs light in red and blue regions of the visible light spectrum . Green color is reflected by them which give green appearance to them.

D) The correct answer is 1. light dependent reactions and calvin cycle reactions.

Photosynthesis takes place in two phases: Light dependent reaction which generate ATP and NADPH and light independent reactions (calvin cycle) which use the chemical energy generated to form carbohydrate molecules from carbon dioxide.

E) The correct answer is 3. Autotrophs.

Autotrophs are those organisms which synthesize their own food by process of photosynthesis.

F) The correct answer is 3. At or by an enzyme in the thylakoid membrane.

ATP is synthesized by ATP synthase in the thylakoid membrane in chloroplast.

G) The correct answer is 4. Less ATP is made.

Protons get released into thylakoid lumen generating a proton gradient . Thylakoid membrane is impermeable to protons . If thylakoid membrane become fully permeable then gradient will be disturbed and less ATP will be made.

H) The correct answer is 2.  wavelength corresponding to red and blue light

Chlorophyll pigment absorb red and blue region of visible light spectrum . It reflect green light thereby giving green color to plants.

I) Ribulose 1,5 - bisphosphate (RuBP) is an organic molecule which is involved in photosynthesis produced in the calvin cycle by phodphorylation of ribulose 5 - phosphate by ATP.

An enzyme ribulose catalyzes the reaction between RuBP and carbon dioxide to produce six-carbon intermediate known as 3-keto-2-carboxyarabinitol 1,5-bisphosphate which decays into two molecules of 3-phosphoglycerate (3-PGA) . Ribulose also known as RuBisCo also catalyzes a reaction between RuBP and oxygen in a process called photorespiration. During photorespiration RuBP combines with Oxygen to produce 3- phosphoglycerate and  phosphoglycolic acid.
