Question 5

whats an organelle

Answer 5

structure of the cell preforming a job

Question 6

how is the mitochondria different than other organelles

Answer 6

it has its own DNA and can self replicate

Question 7

what does anaerobic mean

Answer 7

energy producing that does not used oxygen and is found in cytosol

Question 8

what are the two sub categories of anaerobic metabolism

Answer 8

immediate ATP-PC and Glycosis

Question 9

what is ATP-PC

Answer 9

adenosine triphosphate (ATP) and phosphocreatine (PC). This energy system provides immediate energy through the breakdown of these stored high energy phosphates.

Question 10

what is glycosis

Answer 10

the breakdown of glucose by enzymes, releasing energy and pyruvic acid.

Question 11

What energy nutrient is used by glycolysis to make adenosine triphosphate, ATP, the common energy currency

Answer 11

glucose

Question 12

how much energy does anaerobic metabolism produce

Answer 12

2 ATP

Question 13

what organelle produces most of our bodies ATP

Answer 13

Mitochondria

Question 14

where does the citric acid cycle take place

Answer 14

matrix of the mitochondria

Question 15

whats the purpose of the citric acid cycle

Answer 15

provides the electrons that fuel the process of oxidative phosphorylation

Question 16

where does the electron transport chain take place

Answer 16

the christae of the mitocondria

Question 17

what does the electron transport chain do

Answer 17

The electron transport chain is a series of four protein complexes that couple redox reactions, creating an electrochemical gradient that leads to the creation of ATP in a complete system named oxidative phosphorylation.

Question 18

what is aerobic metabolism

Answer 18

uses 02 takes place in the mitochondria, long term energy over 3 minutes

Question 19
