Who needs the most calories people who are active or people that is not active?
Active people need more calories because in order to have energy and be active, one needs to intake food to burn off as chemical energy.
What two changes of state does this process involve?
In order to know what two changes of state are involved in a process one needs to know what the process is.
Is Liquid water turning to ice a endothermic or exothermic process?
The process of freezing is an exothermic process. Particles in a liquid have more energy than those in a solid, hence they vibrate / move more. Therefore, to turn a liquid into a solid, energy needs to be taken out of the liquid. This means energy is given off to its surroundings, making it an exothermic process.
What is the role of the electrons in the ETC?
Active transport is moving substance against its gradient so it requires an input of energy to achieve this. One example is Na K ATPase. This is a secondary active transporter that pumps 3x Na out of the cell for 2x K into the cell. There are so much more Na outside the cell and already a lot of K inside the cell so to push the molecules there is an expenditure of ATP to do this.
Is it true that the temperature of a substance changes from liquid to gas?
No. the temperature doesn't change, the substance does. yes the temperature of a substance alway changes from liquid to gas because it needs more kinetic energy for a liquid to go to the gas state breaking the intermolecular forces
What type of transport needs energy?
Active transport needs energy, passive transport does not need energy.
Which of these changes needs you to supply energy?
chemical energy
Who needs the most calories people who are active or people that is not active?
Active people need more calories because in order to have energy and be active, one needs to intake food to burn off as chemical energy.
What a needs to transport particles by active transport?
Energy
What kind of transport needs energy?
active transport requires energy from the cell
Which kind of cell transport needs energy?
Active transport.
Does active transport use oxygen?
Active transport (or active uptake, as we learnt it ) is moving against the concentration gradient. This requires energy which is why the oxygen is needed (the oxygen producing energy through respiration). It is affected by the concentration of oxygen because the more oxygen, the more energy produced, the faster the process occurs. Diffusion is not affected by the concentration of oxygen because it does not require energy to occur.
What two changes of state does this process involve?
In order to know what two changes of state are involved in a process one needs to know what the process is.
When a substance changes from a solid to a gas it needs to what energy?
gain heat energy.
Why do young children and active teenagers have high energy needs?
They are growing so they need more energy/food. (Also, they are always active.)
Why do children and active teens have high energy needs?
because its healthy
Why does energy change?
energy changes because the energy needs to transfere in order to become heat energy, sound energy.
