Negative Pressure System or to call it simply, Inhalation, is the part of breathing that requires energy. Energy is required for the diaphragm to contract. The diaphragm contracts and moves down, the chest expands, volume of the thoracic cavity and lungs increase. These combined action causes the pressure inside the lung to decrease below that of the atmosphere. As a result, air is pulled into the lungs.

What are the active and passive parts of breathing?

The active part of breathing involves the contraction of the diaphragm and intercostal muscles to expand the chest cavity, allowing air to enter the lungs. The passive part of breathing involves the relaxation of these muscles, causing the chest cavity to decrease in size and air to be expelled from the lungs.


What are passive transport active transport and endocytosis?

These are three different ways that cells have to get things in and out of the cell. Passive transport is movement without the use of energy, active transport requires energy.Active transport requires energy since the molecules are going toward a region that has a higher concentration of that molecule. The cell is 'stuffing' more into itself.Endocytosis means to 'take into the cell'. Usually this a larger molecule and cell must wrap part of itself around the molecule and then can bring it inside. This is a type of phagocytosis (cell eating).This requires energy as well.


What kind of molecules are moved in active transport?

Active transport requires energy, unlike passive transport. The carrier proteins in active transport act as a "pump" ( fueled by ATP) to carry/attach themselfves to useful proteins for the cell.

Is respiration defined as breathing?

Cellular respiration and breathing are 2 separate things. Breathing is a process of inhaling oxygen into lungs and cellular respiration is a process of burning glucose in presence of oxygen to get energy. Hope this helps

How do materials move in and out of cells and animal cells?

Materials can move in and out of animal cells through one of two reasons: Passive transport or active transport. Passive transport happens naturally and requires no energy on the part of the cell. It usually happens through osmosis, diffusion, or facilitated diffusion. Active transport involves endocytosis, exocytosis, or molecules moving from a low concentration to high concentration. Active transport requires energy.

The movement of substances across the cell membrane that requires the cell to use energy?

It's called active transport. When talking about the cell, it is usually bigger substances that use passages in the cell membrane to access the inner part of the cell, and they need energy to get there. The opposite; passive transport or diffusion, is the movement of dissolved materials through a cell membrane without the use of cellular energy. THis happens with smaller substances.


Are protein part of cell membranes and store energy?

no proteins do not store energy they help active transport


Do facilitated diffusion require energy?

No energy is needed because it's a part of passive transport, not active transport.


What do you do when you are singing a song at karaoke and reach a part that requires a high note?

When singing a song at karaoke and reaching a part that requires a high note, you can try to hit the note by practicing beforehand, using proper breathing techniques, and adjusting your vocal range if needed.
