“Investigate the factors affecting the rate of yeast respiration” Lab Report Introduction The aim of this experiment was to investigate the effect of different amounts of a substrate on the respiration rate of yeast and to compare this to the effect of different amounts of glucose on the rate of yeast respiration. The substrate which I chose to further investigate was fructose. Fructose is a fruit sugar which is one of the three‚ along with glucose and galactose‚ dietary monosaccharides that

Unit 5 Describe the two process by which hormones can cause certain genes to be turned on. (4) Any 2 from: - A hormone binds to a receptor in the cell surface membrane - Idea of the receptor causing (chemical) changes inside the cell - A (functional) {second messenger} activates an {enzyme/transcription factor/eq} Any 2 from: - Idea of a hormone entering the cell through the cell membrane - The hormone binds to a receptor - The {hormone-receptor complex/eq} acts as a transcription factor

run out and organisms would die. The amount of carbon nitrogen and oxygen on the earth is fixed‚ they can exists in different forms but no more may be added. So that these don’t run out they are cycles so they may be reused. Photosynthesis and respiration are the reverse of each other‚ and you couldn’t have one without the other. Carbon is an essential component of all organic substances‚ necessary in nucleic acids‚ proteins‚ carbohydrates. The only way that can enter ecosystems is when it’s used

Seven characteristics of life In life‚ there are seven different characteristics these being; movement‚ excretion‚ respiration‚ reproduction‚ irritability‚ nutrition and growth. Below‚ I will explain each of the characteristics in detail. Reproduction means; “the production of offspring by a sexual or asexual process” (oxford concise colour medical dictionary‚ 2007). Animals and plants do this in different ways‚ animals need two parents‚ and therefore the offspring will share both of the parent’s
