cell membrane - A cell structure that controls which substances can enter or leave the cell. Cytoplasm - A jellylike fluid inside the cell in which the organelles are suspended Where is DNA found? - chromosomes Where is RNA found? - nucleolus Nucleolus - Dense area within the nucleus. Function of RNA - Carry genetic information or instructions form the DNA to the manufacturing parts of the cell Organelles are - Small functioning cell parts Mitochondria are responsible for - Energy produc...

Chloroplast of plants - ANSWER photosynthesis converts energy from the sun into glucose and oxygen Glucose is broken down - ANSWER In the mitochondria through a process called cellular respiration, releasing energy Glycolysis, the Kreb's cycle , and electron transfer chain - ANSWER Process of cellular respiration is comprise of 3 stages Glycolysis - ANSWER First step of cellular respiration, where one molecule of glucose is broken into 2 molecules of pyruvic acid Cytoplasm cells - A...

AQA A LEVEL RESPIRATION EXAM QUESTIONS WITH ANSWERS VERIFIED. Suggest the advantages of the change in blood flow in blood vessels during exercise. [3 marks] -more blood flow to muscles during exercise -supplying more glucose and oxygen/ removing carbon dioxide/ lactic acid/ heat -for high rate of respiration/ to meet increased demand for energy Explain how microorganisms contributed to the increase in temperature during processing of organic waste. [2 marks] respiration produces heat ex...

Structure of Nucleus. - 1. Nuclear envelope: double membrane surrounding nucleus, outer membrane continuous with the (R)ER of the cell. 2. Nuclear pores: allow the passage of larger molecules, such as mRNA, out of the nucleus. 3. Nucleoplasm: granular, jelly-like material making up the bulk of the nucleus. 4. Chromosomes: protein-bound, linear DNA. 5. Nucleolus: small spherical region(s) in nucleoplasm. Manufactures ribosomal RNA and assembles ribosomes. Function of Nucleus. - 1. Controls...

Metabolism correct answer: All of the chemical reactions that occur within an organism cellular metabolism correct answer: chemical reactions within cells nutrient pool correct answer: Accessible sources of organic nutrients metabolic turnover correct answer: Breaking down and replacement of organic components Anabolism correct answer: the synthesis of new organic molecules (from smaller molecules) catabolism correct answer: the breakdown of organic substrates into smaller m...
