is a diagram of a cell carrying out one type of respiration. The arrows show the direction of movement of the substances involved in respiration in this type of cell. A oxygen B carbon dioxide State the type of respiration shown by . Identify the substances involved in respiration that are represented by the letters A and B in . A B State the process by which oxygen moves into the cell. State three processes that require energy from respiration. Some students investigated the effect of temperature on respiration in yeast. • The students put a beaker containing 20 cm3 of a yeast suspension into a water‑bath at different temperatures. • They collected the gas released by the yeast cells in a gas syringe. • They recorded the volume of gas released after 15 minutes. Table 5.1 shows the results. Table 5.1 temperature / °C volume of gas collected in 15 minutes / cm3 0.5 2.8 5.6 9.2 18.2 16.3 10.4 0.3 0.1 0.1 Using the data in Table 5.1, describe the effect of temperature on the rate of respiration in yeast.
