processes in our bodies (king). However‚ from here in the process can turn aerobic‚ meaning using oxygen if present or anaerobic meaning when oxygen is not present in a process called fermentation. The process of fermentation creates two ATP and CO2 molecules and 2 three carbon molecules opposed to the 34 made in the aerobic process called the electron transport chain. Fermentation happens especially when a quick source of energy is needed due to the fast use of oxygen in the aerobic part of respiration

processes of aerobic respiration and photosynthesis. To start‚ aerobic respiration can be defined as a biochemical pathway through which chemical bond energy is released from food and changed into ATP. On the other hand‚ photosynthesis is manufacturing of carbohydrates out of CO2 and the splitting of water in the presence of light. Photosynthesis and aer. respiration can be the same in many ways. For instance‚ both of them contain cycles. In photosynthesis‚ there is the Calvin cycle‚ and photosystem

Design Experiment to investigate the effect of the concentration of Sodium Hydrogen Carbonate on the rate of photosynthesis using Cobomba plant. Aim: The aim of the experiment is to investigate the effect of the concentration of Sodium Hydrogen Carbonate (NaHCO3) on the rate of photosynthesis using a Cobomba plant. Hypothesis: As the concentration of NaHCO3 increases the rate of photosynthesis of the Cobomba plant should increase‚ as there is a greater presence of a carbon dioxide‚ obtained

Abstract: Two parts of this lab were performed involving photosynthesis and cellular respiration. The first part of the lab consisted of cutting out spinach leaf disks with a straw and then putting them into syringes containing an infiltration solution and sodium bicarbonate. Then the syringes were place under the presence of light and watched as certain disks floated. This part of the lab consisted of watching photosynthesis take place. Then for the second part of the lab we tested cellular respiration

Effect of changes in substrate concentration on the reaction rate of an enzyme IB biology Internal Assessment 3/23/12 Research Question: Effect of changes in substrate concentration amount on the reaction rate of an enzyme Introduction: In this experiment‚ the substrate is hydrogen peroxide. The purpose of this investigation is to find out the relationship between the substrate concentration and the rate of reaction. Substrates are molecules that are acted upon by enzymes. For instance

Plan a procedure that will allow you to compare quantitavely the glucose concentration in fresh samples of orange‚ lemon and grapefruit juice. Aim: The aim of this investigation is to produce a set of data which will enable comparison of the glucose concentrations of orange‚ lemon and grapefruit juice. Research: Benedict’s Reagent is a mixture of sodium compounds and copper sulphate. The copper ions are reduced by fructose (a reducing sugar) to form copper oxide‚ thus turning it from blue

Photosynthesis Lab Report Purpose: To research the effect of different wavelengths (colors) of light on plant growth during photosynthesis. Background Information: Photosynthesis is the process by which sunlight is captured by chloroplasts within plant cells and turned into energy. This energy is used to help the plant grow roots‚ leaves‚ flowers and fruit. Energy is required by living things
