question 1/4

What is the purpose of cellular respiration?

Breakdown glucose to produce energy for the cell

Convert solar energy from the sun to chemical energy

Collect

Turn carbon dioxide from the air into sugar

question 2/4

Which choice lists the two types of cellular respiration?

light-dependent & light-independent

Collect

passive & active

aerobic & anaerobic

question 3/4

What organisms do anaerobic respiration and what do aerobic respiration?

anaerobic - most eukaryotes and prokaryotes aerobic - some prokaryotes (bacteria, archaea, fungi)

Collect

aerobic - most eukaryotes and prokaryotes anaerobic - some prokaryotes (bacteria, archaea, fungi)

question 4/4

How is cellular respiration a redox reaction?

because it uses light energy to split water molecules

Collect

because it involves the transfer of electrons between molecules, where glucose is oxidized and oxygen is reduced

because it directly produces oxygen from glucose

Well done!

QUESTION 1/4

Which choice lists the products of glycolysis (per one glucose molecule) and where it occurs?

products - 2 pyruvate molecules, 2 ATP, 2 NADH location - occurs in the cytoplasm of the cell

products - 1 glucose molecule and 4 ATP location - occurs in the mitochondria of the cell

Milking

products - 3 pyruvate molecules and 2 NADPH location - occurs in the nucleus of the cell

QUESTION 2/4

Which choice lists the products of the intermediate step?

Milking

glucose molecules and ATP

Acetyl-CoA, NADH, and CO₂

pyruvate, NADH, and FADH₂

question 3/4

Which choice lists the products of the Krebs cycle (per one glucose molecule) and where it occurs?

products - 4 NADH, 2 FADH₂, 6 ATP, and 2 CO₂ location - occurs in the cytoplasm

Milking

products - 2 NADH, 2 FADH₂, 2 ATP, and 2 CO₂ location - occurs in the nucleus

products - 6 NADH, 2 FADH₂, 2 ATP, and 4 CO₂ location - occurs in the mitochondrial matrix

question 4/4

Where in the cell is the electron transport chain located?

it is located in the inner mitochondrial membrane

Milking

it is located in the nucleus

it is located in the cytoplasm

Well done!

QUESTION 1/4

Where do electrons come from?

electrons come from oxygen

electrons come from NADH and FADH₂

Feed

electrons come from glucose

QUESTION 2/4

What happens in the intermembrane space as electrons go down the electron transport chain and what is its purpose?

protons (H⁺) are pumped from the matrix into the intermembrane space, creating an electrochemical gradient which is then used to make ATP in a process called chemiosmosis

protons are pumped into the nucleus, where they directly interact with DNA to produce ATP

Feed

the intermembrane space fills with oxygen, which is directly converted into water and used to create ATP without the proton gradient

QUESTION 3/4

How is water byproduct produced?

at the end of the ETC, electrons are transferred to oxygen (the final electron acceptor), and oxygen combines with protons (H⁺) to form water

Feed

during glycolysis, when glucose is broken down into pyruvate, water molecules are released as byproduct

water is produced during the citric acid cycle when glucose is converted into water along with ATP

QUESTION 4/4

What are the products of the electron transport chain (per one glucose molecule)?

2 ATP, 2 NADH, and 6 CO₂

Feed

6 H₂O (water) and 32-34 ATP

glucose, oxygen, and FADH₂

Well done!

question 1/4

What are the products of lactic acid fermentation (per one glucose) and where does it occur?

products - 2 lactate and 2 ATP location - occurs in the cytoplasm

products - glucose and carbon dioxide location - occurs in the mitochondria

Shearing

products - oxygen and water location - occurs in the nucleus

question 2/4

Which of the following is an example of when lactic acid fermentation happens?

it happens in plants during photosynthesis when they produce glucose and oxygen

Shearing

it happens in bacteria when they undergo aerobic respiration in the presence of oxygen

it can happen in muscle cells during intense exercise when oxygen supply is insufficient for aerobic respiration

question 3/4

Which choice lists the final products of alcohol fermentation (per one glucose) and where it occurs?

products - 2 ethanol, 2 CO₂, 2 ATP location - occurs in the cytoplasm

Shearing

products - lactic acid and 2 ATP location - occurs in the nucleus

products - oxygen and water location - occurs in the mitochondria

question 4/4

Which of the following is an example of a use of alcohol fermentation?

the production of oxygen in plant cells during photosynthesis

the production of alcoholic beverages (such as beer or wine) by yeast, which ferments sugars to produce ethanol and carbon dioxide

Shearing

the conversion of glucose to lactic acid in muscle cells during intense exercise

Well done!
