Unit 5 - Cell Energy and Transport Storyboard - Tyler McCoy
Текст на Статията
- Chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures like wood trunks and leaves.
- Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water
- Cellular respiration is the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.
- Mitochondria -Performs cellular respiration, forms ATP, and oxidizes food to provide energy to cells
- Carbbon dioxide
- Fermentation is the breaking down of sugar molecules into simpler compounds to produce substances that can be used in making chemical energy.
- The difference
- Passive transport is the movement of substances across the membrane withoutthe expenditure of cellular energy. In contrast, active transport is the movement of substances across the membrane using energy from adenosine triphosphate (ATP)
- Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.
- Photosynthesis makes the glucose that is used in cellular respiration to make ATP. ... While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration.
