Unit 6: Cellular Respiration

Question 1

What do mitochondria do?

Answer 1

Cellular respiration which means the burn glucose to make ATP (energy).

Question 2

What kinds of cells have mitochondria?

Answer 2

All eukaryotes: Animal, PLANT, protist, Fungus

Question 3

What two things need to arrive at a mitochondrion for it to do its job?

Answer 3

Oxygen and Glucose

Question 4

What are the reactants of cellular respiration?

Answer 4

Glucose and Oxygen

Question 5

What are the products of cellular respiration?

Answer 5

Carbon dioxide and Water

Question 6

What is the cellular respiration equation?

Answer 6

In words: Glucose and Oxygen react to produce Water and Carbon dioxide

In symbols:

Question 7

Explain what this image is showing.

Answer 7

During photosynthesis Carbon dioxide and water go to a chloroplast and, in the presence of sunlight, are converted into Oxygen and Glucose. That Oxygen and Glucose go to a Mitochondrion and are converted into Carbon Dioxide and ATP during Cellular respiration.

Question 8

What are the 4 steps of Cellular respiration?

Answer 8

Glycolysis, Citric Acid Cycle, ETC, Water formation

Question 9

Honors: What happens during the First step of Cellular Respiration?

Answer 9

Glycolysis: 6 carbon glucose is broken into 3 carbon Pyruvate

Question 10

Honors: What happens during the Second step of Cellular respiration?

Answer 10

Citric Acid Cycle: 3 Carbon Pyruvate is converted into Carbon dioxide and NADH is produced

Question 11

Honors: What happens during the Third step of Cellular respiration?

Answer 11

Electron Transport Chain: A high concentration of H+ builds up and pushes through the ATP synthase, creating ATP

Question 12

Honors: What happens during the 4th step of Cellular respiration?

Answer 12

Water formation: H+ from the ATP synthase, electrons from the ETC, and Oxygen gas combine to form water.

Question 13

Compare and contrast photosynthesis and cellular respiration

Answer 13

Both involve water, glucose, carbon dioxide, and oxygen. Both involve energy. Their equations are opposites. They happen in different organelles. PS stores energy in glucose and CR releases that energy.

Question 14

What is aerobic respiration?

Answer 14

This is the type of cellular respiration we usually do. Glucose is burned by mitochondria in the presence of Oxygen to make energy.

Question 15

What is anaerobic respiration?

Answer 15

This is the type of cellular respiration done by yeast, bacteria, or us when we’re sprinting. This is glucose being broken down without using Oxygen in order to make some energy.

Question 16

Compare and Contrast Aerobic and Anaerobic respiration

Answer 16

Both make ATP. Aerobic is more efficient and requires Oxygen. Bacteria can’t do aerobic respiration.

Question 17

What are two types of anaerobic respiration?

Answer 17

Alcohol fermentation- when yeast make bread, beer, or wine Lactic acid fermentation- when bacteria make yogurt and cheese or muscle cells make enough energy to not die.

Question 18

Will a plant in sunlight produce more Oxygen or Carbon dioxide? Why?

Answer 18

A plant in sunlight produce more Oxygen because it will do more photosynthesis than cellular respiration. Oxygen is produced during photosynthesis.
