Lab 2 Exam

Question 1

Difference between photochemical light reaction
Vs
Biochemical dark reaction

Answer 1

photochemical light reaction: Fast , Light-dependent, Splits water to release oxygen, electrons, and protons

Biochemical “Dark” Reactions:Slower, but still extremely fast Light-independent, Reduces carbon dioxide to sugar

Question 2

Like produces reactions only if

Answer 2

It is absorbed by molecule

Question 3

What is responsible for the plant green color?

Answer 3

Greenlight

Question 4

What is the process of the absorbed light?

Answer 4

Absorb light excites the chlorophyll by boosting electrons to a higher of energy orbital

Question 5

What happens during photosynthesis with the energy?

Answer 5

The energy of the excite electrons from chlorophyll and chlorophyll central magnesium atom to another pigment molecule and photosynthesis proceed.

Question 6

How can the photosynthetic disrupt?

Answer 6

You can just drop by bleeding cells during preparation

Question 7

What happened to the energy when electrons return to the original orbital?

Answer 7

The energy is passed, efficiently to another pigment molecule as light is harvested

Question 8

What is the term when a photon of red light is admitted to the electron returns to its orbital the release of the energy is called

Answer 8

Fluorescence

Question 9

Can chlorax transfer electrons in absence of CO2

Answer 9

Yes, it can transfer electrons in the absence of CO2. It provides an alternate or artificial electronic acceptor.

Question 10

How can you detect electrons transfer?

Answer 10

Using a dye, that’s called two, six dichlorophenol-indolphenol (DCPIP)

Question 11

What is Phenol red

Answer 11

It’s an indicator for pH, that turns yellow and aesthetic solution, and becomes red out of neutral to basic solution

Question 12

How do you detect CO2?

Answer 12

If you put a plant into the environment and you make slightly acidic with your breath

Question 13

The right dependent reaction of photosynthesis occurs on what

Answer 13

Photosynthetic membranes

Question 14

What is photosynthetic membranes called
What do they do? Where are they located?

Answer 14

thylakoids and are located within chloroplast
a chloroplast, an organelle specialized for photosynthesis
Thylakoids form stacks called grana, which are connected by lamellae.
Lamellae is The semi-liquid stroma of the chloroplast interior contains the enzymes that catalyze the light-independent reactions of photosynthesis.

Question 15

Sugars produced by photosynthesis are often stored
To produce this starch
Photosynthesis also requires

Answer 15

Starch

photosynthesis requires light as an energy source.

chlorophyll to capture light energy.
