mini-quiz G

Question 1

What is the final electron acceptor in oxidative phosphorylation in animals ?

Answer 1

Oxygen

Oxygen plays a critical role in cellular respiration by accepting electrons at the end of the electron transport chain.

Question 2

What two processes are combined in oxidative phosphorylation?

Answer 2

Electron transport chain & ATP syntase

This combination is essential for the production of ATP in aerobic respiration.

Question 3

What is the starting molecule for glycolysis?

Answer 3

Glucose

Glycolysis is the first step in the breakdown of glucose to extract energy.

Question 4

What is produced from glyceraldehyde 3-P during glycolysis?

Answer 4

Pyruvate

Pyruvate is the end product of glycolysis and can be further utilized in aerobic or anaerobic pathways.

Question 5

What is the molecule that links glycolysis to the citric acid cycle?

Answer 5

Acetyl CoA

Acetyl CoA is formed from pyruvate and enters the citric acid cycle for further energy production.

Question 6

What is the main function of the citric acid cycle?

Answer 6

To generate electron carriers

The citric acid cycle produces NADH and FADH2, which are essential for the electron transport chain.

Question 7

Fill in the blank: The building blocks of proteins are _______.

Answer 7

Amino acids

Amino acids are the fundamental units that make up proteins.

Question 8

What are the primary components of carbohydrates?

Answer 8

Sugars

Carbohydrates are organic compounds made primarily of carbon, hydrogen, and oxygen, with sugars being the simplest form.

Question 9

What are the primary components of fats?

Answer 9

Glycerol & Fatty acids

Fats are made up of glycerol and fatty acid chains, which are important for energy storage.

Question 10

2 Things Pyruvate Can Be Converted into in Anaerobic Respiration

Answer 10

Lactate and Ethanol

Question 11

Autotrophs

Answer 11

Self-feeders

Question 12

Heterotrophs

Answer 12

Other feeders

Question 13

2 Types of Autotrophs

Answer 13

Phototrophs and Chemoautotrophs

Question 14

2 Types of Heterotrophs

Answer 14

Consumers and Deconposers

Question 15

3 Main Components of Leaf Anatomy

Answer 15

Epidermal cells (outer), Mesophyll cells (middle), and Stomata (bottom, openings on leaf bottom)

Question 16

Which cells in a leaf contain chloroplasts?

Answer 16

Mesophyll cells

Question 17

What is the wavelength of visible light on the electromagnetic spectrum?

Answer 17

380 nm - 750 nm

Question 18

True or false: larger wavelengths have greater energy in the electromagnetic spectrum.

Answer 18

False. Smaller wavelengths have more energy.

Question 19

Which visible wavelengths on the electromagnetic spectrum are most commonly used for energy?

Answer 19

The 400-500 nm and the 600-700 nm wavelengths are most commonly used for energy.

Question 20

2 types of pigment molecules

Answer 20

Chlorophylls (greens) and Carotenoids (reds, oranges, & yellows)

Question 21

What are photosystems (PS)?

Answer 21

PS are complexes of pigments and proteins.

Question 22

What are light harvesting complexes (LHC)?

Answer 22

LHC are 200-400 pigment molecules and a couple proteins. They are also known as “antenna complexes”.

Question 23

What are reaction center complexes (RCC)?

Answer 23

RCC are primarily comprised of proteins. However, they also contain two special chlorophyll molecules that absorb energy. This increase in energy causes the electron to become “super excited”.

Question 24

2 Slightly Different Photosystems…

Answer 24

Photosystem I and Photosystem II
