What are the 3 main differences between plant and animal cells?
Major structural differences between a plant and an animal cell include:
- Plant cells have a cell wall, but animals cells do not.
- Plant cells have chloroplasts, but animal cells do not.
- Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles, if any are present.
Which macromolecule found in the food you eat will be broken down for energy first to get ATP?
glucose
Why is energy not released soon after eating?
Post-meal, the body streams more blood to the digestive system to better digest foods in massive amounts. This causes a temporary blood and nutrients shortage in the brain. To prevent post-meal drowsiness, it’s better to eat a balanced diet containing vegetables, grains and good fats to provide continuous energy.
What happens when glucose is broken down in the absence of oxygen?
in the absence of oxygen in which glucose breaks into alcohol and carbon dioxide with release of energy. It takes place in yeast cells. Glucose –> ethanol + carbon dioxide + energy. In absence of oxygen in our muscle cells, Glucose breaks into lactic acid with the release of energy.
What will happen if glucose breaks down in lack of oxygen?
If oxygen is present, then glucose can be broken all the way down into carbon dioxide and water. This process is called aerobic respiration because it requires air (oxygen). In the absence of oxygen, the cell uses a process called anaerobic fermentation. or simply fermentation.
Which cell breaks down sugar into energy?
cellular respiration
What is the main source of energy for cells?
Why is the absence of a cell wall an advantage for animal cells?
Answer: Animals do not have cell wall cause they don’t need them , cell wall which are found in cell, maintain cell shape almost as if each cell has it’s own exoskeleton . this rigidity allows plants to stand upright without the need for bones .
What is the source of instant energy for living cells?
ATP
Why is oxygen important to blood and to the cell?
(We breathe because oxygen is needed to burn the fuel [sugars and fatty acids] in our cells to produce energy.) What happens in the process of respiration? (Oxygen is brought into the lungs via breathing, where it is transported by red blood cells to the entire body to be used to produce energy.
