Showing Results for "photosynthesis"

Photosynthesis

Photosynthesis is the process by which green plants , algae , and some bacteria convert light energy , carbon dioxide , and water into glucose and oxygen . This process takes place in the chloroplasts of plant cells and involves two main stages: the light -dependent reactions and the light -independent reactions (Calvin cycle).

Light -Dependent Reactions:

• Light energy is absorbed by chlorophyll and other pigments in the thylakoid membranes of the chloroplasts .
• This energy is used to split water molecules into oxygen , protons , and electrons . The oxygen is released as a byproduct.
• The electrons are transferred through a series of proteins , creating a flow of hydrogen ions across the thylakoid membrane.
• This flow of hydrogen ions drives the production of ATP and NADPH , which are used to power the light -independent reactions.

Light -Independent Reactions (Calvin Cycle):

• The ATP and NADPH produced in the light -dependent reactions are used to convert carbon dioxide into glucose in a series of enzyme-catalyzed reactions.
• This process also regenerates the molecule that captures carbon dioxide , allowing the cycle to continue.

Respiration

Cellular respiration is the process by which cells break down glucose and other organic molecules to produce ATP , the primary energy currency of cells . This process occurs in the mitochondria of eukaryotic cells and involves three main stages: glycolysis, the citric acid cycle, and oxidative phosphorylation.

Glycolysis:

• Glucose is broken down into two molecules of pyruvate in the cytoplasm of the cell , producing a small amount of ATP and NADH.

Citric Acid Cycle:

• Pyruvate is transported into the mitochondria and converted into acetyl CoA, which enters the citric acid cycle.
• During the citric acid cycle, acetyl CoA is further broken down, releasing more ATP , NADH, and FADH 2 .

Oxidative Phosphorylation:

• The high- energy electrons carried by NADH and FADH 2 are used to generate a large amount of ATP through a series of protein complexes in the inner mitochondrial membrane.
• Oxygen acts as the final electron acceptor, forming water as a byproduct.

Study Guide

When studying photosynthesis and respiration , it's important to understand the key concepts, processes, and the interrelationship between the two. Here are some key points to focus on:

• Understand the overall chemical equations for photosynthesis and respiration , including the reactants and products involved.
• Learn the specific reactions and enzymes involved in each stage of photosynthesis and respiration , and the locations within the cell where these processes occur.
• Be able to explain the role of ATP , NADPH , NADH, and FADH 2 in energy production and transfer during these processes.
• Understand the relationship between the light -dependent and light -independent reactions in photosynthesis , as well as the interconnected nature of glycolysis, the citric acid cycle, and oxidative phosphorylation in respiration .
• Be able to compare and contrast the inputs, outputs, and overall purposes of photosynthesis and respiration in maintaining the energy balance of living organisms .

AP Biology - Investigation: Photosynthesis

Background and prelab (view as google doc ).

Photosynthesis fuels ecosystems and replenishes the Earth's atmosphere with oxygen. Like all enzyme-driven reactions, the rate of photosynthesis can be measured by either the disappearance of substrate, or the accumulation of products. The equation for photosynthesis is:

6CO 2 + 6H 2 O ------light--------> C 6 H 12 O 6 + 6O 2 + H 2 0

To determine the rate of photosynthesis, you could measure the production of oxygen, which is released when photosynthesis occurs or the consumption of carbon dioxide.

Leaf Structure and Function

In this investigation, you will use a system that measures the accumulation of oxygen in the leaf. Consider the anatomy of the leaf. The leaf is composed of layers of cells. The spongy mesophyll layer is normally infused with gases, oxygen and carbon dioxide. Leaves (or disks cut from leaves) will normally float in water because of these gases. If you draw the gases out from the spaces, then the leaves will sink because they become more dense than water. If this leaf disk is placed in a solution with an alternate source of carbon dioxide in the form of bicarbonate ions, then photosynthesis can occur in a sunken leaf disk. As photosynthesis proceeds, oxygen accumulates in the air spaces of the spongy mesophyll. The leaf becomes buoyant and floats.

While this is going on, the leaf is also carrying out cellular respiration. This respiration will consume the oxygen that has accumulated and possibly cause the plant disks to sink. In other words, the buoyancy of the leaf disk is actually an indirect measurement of the NET rate of photosynthesis occurring in the leaf tissue.

Experimental Question: What factors affect the rate of photosynthesis?

Pre-lab Questions - these should be completed before the scheduled lab.

1. How can the rate of photosynthesis be measured?

2. Where in the cell of the leaf do you find air spaces?

What is the function of the stomata?

3. What will happen if you remove the air from these spaces?

How will air return to these spaces?

4. Instead of carbon dioxide, what will be used to as the reactant in this lab?

5. List any factors that you think may affect the rate of photosynthesis. Consider environmental factors that you could manipulate during the lab.

Baking soda | Liquid soap | Plastic syringes (10 mL or larger) | Leaves (spinach or ivy) | Hole punch or Straws | Cups or beakers | Timer | Light source

Analysis: To make comparisons between experiments, a standard point of reference is needed. Repeated testing of this procedure has shown that the point at which 50% of the disks are floating (ET50) is a reliable and repeatable point of reference.

Graph your data for the experiment. X-axis is Time (min) and Y-axis is # floating disks.

Be sure to include a key for each sample set. There should be four lines on your graph. Determine the ET50 for each set of leaf disks.

Conclusion:

What is the relationship between the variables aand photosynthesis rate? This is your CLAIM .

What evidence supports those claims (summarize data)?

Provide reasoning that linke the evidence and the claim and explains why this relationship exists. A discussion of photosynthesis is appropropriate in this section.

A newer version of this lab is available which includes an INQUIRY activity and allows students freedom to collect data on different variables: Investigation: Photosynthesis
