Compare photosynthesis and cellular respiration

The end result is glucose, with oxygen being the waste product. The italicized terms indicate environmental factors that control the fluxes.

The particular action illustrated here is called the pump handle movement of the rib cage. They might analyse the advantages and disadvantages of specific adaptations, such as being on 2 feet rather than 4, having a long or a short beak, having gills or lungs, tendrils on climbing plants, brightly coloured and scented flowers.

Decomposition is not the only source of CO2 in soil. Basic scientific experiments, carried out using cells from chicken lungs, support the potential for using steroids as a means of furthering development of type II alveolar cells.

In the atmosphere, carbon is in the form of carbon dioxide gas. The focus at this stage should be on questions that help pupils to recognise growth; they should not be expected to understand how reproduction occurs.

National curriculum in England: science programmes of study

They should ask their own questions about what they observe and make some decisions about which types of scientific enquiry are likely to be the best ways of answering them, including observing changes over time, noticing patterns, grouping and classifying things, carrying out simple comparative and fair tests and finding things out using secondary sources of information.

During the Pennsylvanian Period, the earth was covered with huge swampy forests of giant ferns, horsetails, and club mosses. In humans, aerobic conditions produce pyruvate and anaerobic conditions produce lactate.

Although the spatial relationship between granum and stroma thylakoids has been known for more than 20 years, most textbooks and research papers continue to include erroneous 3D models and simplified schemes.

Replace the chamber and place a weight on it like a fist-sized rock or a thick branch to maintain pressure and keep it from blowing away or tipping over. CO2 diffuses from the soil into the chamber air space.

These opportunities for working scientifically should be provided across years 3 and 4 so that the expectations in the programme of study can be met by the end of year 4.

The citric acid cycle is an 8-step process involving 18 different enzymes and co-enzymes. Everyday materials Pupils should be taught to: This rapid increase will likely lead to a cascade of environmental impacts such as global warming, sea level rise, alteration of precipitation patterns, and increased storm severity IPCC Show it to your Instructor for approval before proceeding.


Every cycle pumps three sodium ions out of the axon and two potassium ions into the axon. Several environmental factors control the rates of decomposition and root respiration and therefore, the rate of CO2 emission from soils. Year 1 programme of study Plants Pupils should be taught to: The two processes are similar in that they both produce energy, albeit in two different forms.

In humans, gut flora synthesize folic acid from this molecule. Before leaving the site quantify the differences in environmental factors between your two sampling sites. Boxes represent amounts of carbon mass and arrows represent fluxes mass per unit area per unit time.The respiratory system (also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for gas exchange in animals and anatomy and physiology that make this happen varies greatly, depending on the size of the organism, the environment in which it lives and its evolutionary history.

Respiration, carbon dioxide gas is produced during respiration See diagram Lime water test for carbon dioxide in the breath Plants (and animals) breathe in oxygen gas from the air to breakdown food into carbon dioxide gas and water.

LEARNING OBJECTIVES By the end of this lecture you will be able to: Understand that ENERGY can be transformed from one form to another. Know that energy exist in two forms; free energy - available for doing work or as heat - a form unavailable for doing work.

Labs. These are "Simple, Inexpensive Classroom Experiments for Understanding Basic Gas Laws and Properties of Gases". Check out the article, "Inquiry and the Collapsing Can" in NSTA's The Science Teacher, April/Mayp. (members can access the link).And check out the "Collapsing Can" this Cartesian Diver demo to illustrate Boyles's Law.

Welcome to CELLS alive! Explore * Study * Play Cells, Microbes and the Immune System Quick Find: Cellular Glossary. Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.

The reactions involved in respiration are catabolic reactions, which break large molecules into smaller ones, releasing energy in the process, as weak so-called "high-energy.
