How Cells Obtain Energy

Question 1

Energy

Answer 1

Energy is what lets us perform specific functions for the sustainment of our body. It is important

Question 2

Energy cannot…

Answer 2

be destroyed

Question 3

Cells can obtain energy by:

Answer 3

Photosynthesis (PLANT CELLS ONLY), Cellular Respiration (BOTH CELLS), and Fermentation

Question 4

Photosynthesis equation

Answer 4

6CO2 + 6H2O → C6H12O6 + 6O2

Question 5

Cellular Respration Formula

Answer 5

C6H12O6 + 6O2 → 6CO2 + 6H2O

Question 6

Types of Fermentation

Answer 6

Alcoholic Fermentation and Lactic acid Fermentation

Question 7

Lactic acid Fermentation

Answer 7

Happens without oxygen and happens to muscles and yogurt. Creates lactic acid, which results in muscle soreness.

Question 8

Alcoholic Fermentation

Answer 8

Also without oxygen and happens to yeast

Question 9

Photosynthesis is….

Answer 9

the way plants can make their own food with light, water, and carbon dioxide

Question 10

Cellular respiration is….

Answer 10

How food is converted into energy (ATP) in plant and animal cells WITH oxygen present

Question 11

Autotroph

Answer 11

An organism that can make its own food (a plant)

Question 12

Heterotroph

Answer 12

An organism that consumes food (cannot make its own). Humans, dogs, and cats are heterotrophs.

Question 13

Fermentation is..

Answer 13

How food is converted into energy (ATP) in plant and animal cells WITHOUT oxygen present

Question 14

The byproduct of photosynthesis is…

Answer 14

Oxygen

Question 15

The byproduct of cellular respiration is..

Answer 15

Water and Carbon Dioxide

Question 16

The byproduct of alcoholic fermentation is…

Answer 16

Alcohol (in the form of Ethanol)

Question 17

The byproduct of lactic acid fermentation is..

Answer 17

Lactic Acid

Question 18

Photosynthesis takes place in….

Answer 18

the chloroplast of a plant cell. It is green due to the pigment known as chlorophyll

Question 19

Photosynthesis is important because….

Answer 19

it helps plants grow and prosper. Plants are important as food. Also, it releases oxygen as a byproduct, and humans need oxygen to live…

Question 20

Cellular respiration takes place in…

Answer 20

the cytoplasm (FIRST) and then in the mitochondria/mitochondrion (SECOND)

Question 21

Cellular respiration is important because….

Answer 21

it gives us energy. Energy is important and makes us function, and be living in the world.

Question 22

Glycolysis

Answer 22

The first step in cellular respiration

Question 23

Glycolysis occurs in the….

Answer 23

CYTOPLASM

Question 24

Glycolysis is when…

Answer 24

glucose breaks down into smaller molecules and a small amount of ATP is produced

Question 25

Aerobic respiration

Answer 25

Respiration that requires OXYGEN | Example: Cellular respiration

Question 26

Anaerobic Respiration

Answer 26

Respiration that doesn’t require OXYGEN | Example(s): 2 types of Fermentation (Alcohol and Lactic Acid)

Question 27

Alcohol fermentation results in….

Answer 27

Carbon dioxide releasing when the bread rises

Question 28

Fermentation is important because…

Answer 28

it makes Bread rise! Also, during conditions when there is no oxygen, energy can be produced. It can happen when the body needs energy but there is no oxygen present. It keeps us alive in a way.

Question 29

Lactic acid fermentation occurs in…

Answer 29

Muscle cells, and in the CYTOPLASM of a cell.

Question 30

Lactic acid is produced because….

Answer 30

muscle cells or any other cell needs energy. When there is no oxygen, lactic acid builds up as Lactic acid fermentation is the process being used.

Question 31

ATP

Answer 31

Adenosine Triphosphate: This is what makes up the energy in our body and fuels our cells (in the MITOCHONDRIA)
