The process that caused the color change is called
cellular respiration
. … During this process, the snail exhales carbon dioxide, which combines with water to form a weak carbonic acid, which in turn changes the color of the water from blue to yellow.
What does it mean when BTB turns yellow?
BTB is an acid indicator;
when it reacts with acid it
turns from blue to yellow. When carbon dioxide reacts with water, a weak acid (carbonic acid) is formed (see chemical reaction below). The more carbon dioxide you breathe into the BTB solution, the faster it will change color to yellow.
What caused the color of the BTB to change?
What caused the BTB to turn yellow?
Input of carbon dioxide from my breath created carbonic acid, which lowered the pH of the solution
resulting in a color change of the indicator.
What is the process of cellular respiration?
Cellular respiration, the process by
which organisms combine oxygen with foodstuff molecules
, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
What is cellular respiration and photosynthesis?
Photosynthesis converts carbon dioxide and water into oxygen and glucose
. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.
When someone breathes into bromothymol blue and it turns green or yellow Why does it do that?
Breathing rate increases with in increase of physical activity. Bromothymol blue is in indicator for carbon dioxide which means that it will change color if carbon dioxide is present. Bromothymol blue solution changes color from blue to green or from blue to yellow when
carbon dioxide if bubbled into it
.
What color is bromothymol blue in water?
Bromothymol blue acts as a weak acid in a solution. It can thus be in protonated or deprotonated form, appearing yellow or blue, respectively. It is bright aquamarine by itself, and
greenish-blue in a neutral solution
.
What is the original color of bromothymol blue?
Bromothymol blue has
a blue color when in basic conditions
(pH over 7), a green color in neutral conditions (pH of 7), and a yellow color in acidic conditions (pH under 7). So, if we're watching a reaction as it changes pH, we can watch the color change and determine when the pH changes.
How long does it take for BTB to change color?
This investigation is a visual way to introduce students to photosynthesis. As Elodea uses carbon dioxide from the initial solution, a change in pH occurs, causing a color change in the solution. The change is detectable in
as little as 30 minutes to an hour.
What process caused the liquids in D 2 D 3 & D 4 to change from blue to yellow?
The process that caused the color change is called
cellular respiration
. The Bromothymol blue indicator changes from blue to yellow in the presence of an acid.
What are the 3 main stages of cellular respiration?
Aerobic respiration is divided into three main stages:
Glycolysis, Citric acid cycle and Electron transport chain
.
What are the 3 main parts of cellular respiration?
Cellular respiration is made up of three sub-processes:
glycolysis, the Citric Acid Cycle (Krebs Cycle), and the Electron Transport Chain (ETC)
. Let's talk about each one in detail.
What would happen if respiration takes place in single step?
What would be the problem if cellular respiration took place in just one step?
all of the energy would be released at once and most of it would be lost in the form of light and heat
. the cell converts NADH to NAD+ by passing electrons back to pyruvic acid allowing glycolysis and ATP production to continue.
How do photosynthesis and cellular respiration affect humans?
The oxygen produced by plants during photosynthesis is what humans and animals inhale for the blood to transport to the cells for respiration. … The process of photosynthesis is used by plants and other photosynthetic organisms to produce energy, whereas the process of
cellular respiration breaks down the energy for use
.
How are photosynthesis and cellular respiration similar and different?
The two processes are similar in that they both produce energy, albeit in two different forms. They are different in that
photosynthesis assembles the glucose molecule
, while cellular respiration takes it apart.
In what way are photosynthesis and cellular respiration different?
The main difference between photosynthesis and cellular respiration is that
photosynthesis is an anabolic process, where the synthesis of organic compounds occurs
, storing energy whereas cellular respiration is a catabolic process, where the stored organic compounds are utilized, producing energy.
