Lab #2: Energy in Cell Virtual Lab - Week 3
1. What is the importance of the light and dark reactions in photosynthesis?
Photosynthesis works by absorbing light. Our sun gives off energy and the chlorophyll from the plant absorb this energ...
Both photosynthesis and cellular respiration are the main pathways of energy transportation in organisms. However, the reactants and the products are exact opposites in photosynthesis and in cellular respiration.
In photosynthesis, cells take in carbon dioxide (CO2) and water (H2O) by absorbing...
Photosynthesis and cellular respiration play significant roles in existence of all living organisms on the planet. Supplying energy to the cells they carry out is the main process called life. Photosynthesis is the process by which several living organisms such as plants and bacteria utilize sunligh...

Assignment Photosynthesis and Cellular Respiration
Energy acquisition is essential for all life. Whether the organism is classified as plant or animal, single-celled or multi-cellular, the exchange of energy and the formation of products consist of a series of chemical reactions that occur at th...
Cellular Respiration and Photosynthesis
Photosynthesis is the process by which plants, some bacteria, and some protistans use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the "fuel" used by all living things. The conversion of unusable sunlight energ...

Animal and plant cells are very similar in the way that they create energy to perform their duties. The chemical equations are very similar for cellular respiration and photosynthesis are almost exact opposites. Photosynthesis is anabolic; it builds up glucose, or sugar, from light energy, water and...
Cellular Respiration vs. Photosynthesis
To obtain energy needed for life, organisms depend on the processes of cellular respiration and photosynthesis. Though they share the same function of changing energy from one form to another, there are many differences between cellular respiration and pho...
Chapter 6-Intro to Metabolism
METABOLISM= all the chemical reactions in an organism
CATABOLIC PATHWAY (CATABOLISM)• release of energy by the breakdown of complex molecules to simpler compounds
EX: digestive enzymes break down food
ANABOLIC PATHWAY (ANABOLISM)
• consumes energy to...

1. What two molecules are formed when a phosphate is removed from ATP?
There are three phosphate groups in ATP molecule (Adenosine Triphosphate), when removing one phosphate molecule, ADP molecule is formed (Adenosine Diphosphate).
2. What is the function...
Cellular Respiration Project Objective Answers
1. The overall equation for Cellular Respiration is 6O2 + C6H12O6 6H2O + 6CO2 +
energy. Overall, it is the reverse reaction of photosynthesis, but chemically, the steps involved
are very different. All you have to do is just flip both sides of...
1. The survival of every organism depends upon a constant supply of ___________, which can be obtained in one of two ways.
2. The first way to acquire energy is to harness the power of the sun through the process of ____________. The second way is gain the energy that...
Part 1. Cellular Respiration
Partner: Ben Liu
Purpose: To examine the rate of alcoholic fermentation using various carbohydrates.
Hypothesis: If the yeast is placed in 5% glucose or sucrose solutions, then carbon dioxide production will increase over time. I...
Cellular Respiration Questions
Aerobic pathways require oxygen, while anaerobic pathways don't.
Anaerobic pathways only require the process of glycolysis to produce energy. Anaerobic pathways are found outside the mitochondria within the cytoplasm of the cell, with...
AP Biology I
AP Bio: Lab 6 Cellular Respiration
Some knowledge that is needed before performing this lab are as follows: First of all, cellular respiration is the metabolic processes whereby certain organisms obtain energy from organic molecules. This process include...
Photosynthesis and Respiration
In this activity we will review the process of photosynthesis and cellular respiration, and become familiar with the use of a pH indicator for investigating these processes. Following this activity your group will generate a new research question...
The experiment aims to observe if simpler substrates makes the rate of cellular respiration faster. Using yeast, smith fermentation tubes and different substrates namely, starch, lactose, sucrose, glucose and fructose, which are from different kinds of carbohydrates, ranging from...
Cellular Respiration and Fermentation: Experimenting With CO2 and Redox Reactions
Julius Engel; Section 8
In this experiment, the subjects of study were fermentation, mitochondrial respiration, and redox reactions. In the first experiment, yeast was grown in...
Photosynthesis vs. Cell Respiration
Photosynthesis and cellular respiration are both vital to the survival of organisms. They are both similar and different in some ways. Also they work off of each other to continue. But overall without these two processes...
