Investigation 5: Photosynthesis Problem: If the leaf disks are treated in a way you know increases the net rate of photosynthesis‚ should they start to float faster or slower? Why? Hypothesis: If the leaf disks were bathed in a red light source‚ then the rate of photosynthesis would increase than leaf disks that are bathed in a regular light source because chlorophyll absorbs red pigment and reflects green pigments. Therefore‚ shining a red light source onto the leaf disks would cause them

BIOLOGY A REPORT ON RESPIRATION IN INVERTEBRATES COMPILED & PRESENTED BY DEPARTMENT OF ANIMAL AND ENVIRONMENTAL BIOLOGY 2012/2013 SESSION COURSE: FSB201 (CELL BIOLOGY) COURSE LECTURER: DR. NOUTCHA DATE : 7TH MARCH‚ 2013 INTRODUCTION Respiration is one of the characteristics of ALL LIVING THINGS. In the simplest terms‚ "respiration" simply means "breathing". But more formally‚ the term depends on what type of respiration been referred to. Essentially‚ "respiration" refers to gaseous exchange

In the Calvin cycle‚ carbon atoms from CO2 are fixed and used to build three-carbon sugars. This process is fueled by‚ and dependent on‚ ATP and NADPH from the light reactions. Unlike the light reactions‚ which take place in the thylakoid membrane‚ the reactions of the Calvin cycle take place in the stroma. In the Calvin cycle‚ getting pulled into the cells using RUBISCO to facilitate the process incorporated gaseous CO2 molecules. RUBISCO acts much like a sponge with a great absorptive power to

SUSTAINABILITY ASSIGNMENT 1 KHANH NGUYEN 1001974 THE NATURAL CARBON CYCLE Carbon dioxide (CO2) is one of the biogeochemical cycles which the fourth most common elements on Earth. It is also a basis of all life and continually cycled and globally existed. Carbon dioxide is obtained from various sources‚ including emissions from volcanoes or industries and combustion products of organic compounds and the respiratory activity of living organisms. Carbon dioxide not only going into the atmosphere through the

oD 4.1 Respiration Why organisms undergo respiration What is respiration and why do we need it? Respiration is the process whereby energy is released from food molecules (most usually glucose). It takes place inside living cells‚ both eukaryotic and prokaryotic. The process takes place inside the cytoplasm and the mitochondria. Energy is used to synthesise adenosine triphosphate (ATP)‚ which acts as a short-term energy store in cells. All living organisms need energy to drive their

BACCHALAUREATE SIXTH PARTIAL SECOND QUIMESTER How students will be grade on a class project? Topics: Photosynthesis (chapter 7) and Cellular Respiration (chapter 8) Objectives: to explain and describe the metabolism of photosynthesis reactions and respiration reactions Specific objectives: (each one is a topic project) to explain the overall reactions of photosynthesis and respiration as metabolic pathways and coupled reaction. to explain and describe photosynthesis light dependent reaction and photosystems

In the atmosphere was where I started. Seventy five years I was there. A carbon atom in a carbon dioxide molecule was what I was. A Pinyon pine tree going through photosynthesis took me from the atmosphere. After I left my home‚ I converted into a tissue in a Pinyon pine needle. This was only the first part of the cycle‚ and I was going to the biosphere-plant. A new territory‚ the biosphere-plant. Accordingly‚ I existed as a tissue in a Pinyon pine needle. For two months I stayed like that.

Crystal Lewis 9/21/10 Period 1 Carbon Dioxide Carbon Dioxide is the infrastructure of all life on earth. Every human being and animal needs it to survive‚ making it an essential compound. In order to survive‚ humans and animals must give off carbon dioxide to take in oxygen‚ whereas plants must take in the compound and give off oxygen. Carbon Dioxide has numerous unique characteristics‚ properties‚ and safety measures that everyone should be aware of. Being aware of this compound and what it

prokaryotes instead of chloroplast they use their own cell membranes to do the job. Wavelength also has a role in photosynthesis because they have just the right amount of energy to excite chlorophyll electrons boosting them to a higher energy level. When summing everything up the reactants are carbon dioxide‚ water‚ and the suns energy and the process is light dependent and the Calvin cycle. The products include oxygen and glucose. Pigments serve as photosynthetic organisms that capture energy from
