- Definition, Names & List. There's more than one way to make a painting! In this lesson, we will look geometric shapes in art movements as well as the artists who utilize the line-driven making of shapes.
It's really important for you to remember that cellular respiration in eukaryotic cells takes place in the mitochondria. Both animal cells and plant cells depend on cellular respiration for their energy needs, because both animal cells and plant cells need ATP. Plant cells may be able to use the energy from the sun to make sugar, but they can't use the sun's energy as fuel.
Energy is required for cells to perform many functions. Enzymes convert substrates into products but must do so against the activation energy (so energy is needed here). Cellular respiration requires some amount of energy to occur. The most important energy consumer is the Na+/K+ ATPase ion pump which is responsible for maintaining cellular gradients and consumes approximately 50% of the energy of the cell.
