What is created using the sugars that are produced during photosynthesis?

The resting membrane potential is balanced by ion leakage and ion pumping, to get an electrical signal started the membrane potential has to lose its balance. This starts with a membrane channel opening for Na+ since Na+ concentration is higher outside the cell, ions will rush into the cell. This will change the relative voltage inside the cell. The resting potential has a voltage of -70 mV, the sodium cation entering the cell cause it to become less negative. This is known as depolarization.

The concentration gradient for Na+ will continue to enter the cell making the voltage to become positive reaching +30 mV. At the same time, this happens, other voltage-gated channels are also opening, a concentration gradient acts on K+, as well, as it leaves the cell, it takes a positive charge with it making the membrane potential to move back to its resting voltage of -70 mV. This is called repolarization.

For potassium ions to reach equilibrium the membrane voltage needs to be below -70 mV, this leads to a period of hyperpolarization that occurs while the K+ channels are open.

I annexed an image that illustrates this action potential process.

Considering the information given during depolarization there's an increase in the number of sodium leak channels (7) making the inside of the cell more positive (2) increase in the membrane potential (4), this also implies a decrease in the extracellular concentration of potassium (6)

Meanwhile, during hyperpolarization an increase in the extracellular concentration of potassium (3) decreases the membrane potential (1) making the inside of the cell more negative (5).

I hope you find this information useful and interesting! Good luck!

Embryology concerns the structural changes that occur in an individual from conception through old age. true false

Jlenok [28]

False: Development of gametes and embryos.

Development is a human process in the sense that people, not material factors, drive development. The energy and ambition of those who seek development are the driving forces behind the development. People's consciousness can determine the direction of development.

- Can be a source of employment. - Contribute to national development and promote the economy. - Helps develop infrastructure. - Contribute to the preservation of cultural heritage.

Helps businesses attract and retain top talent, improve productivity, and help businesses generate more profit through learning and development.

What function do plants have in the forest in the carbon cycle

statuscvo [17]

Plants absorb carbon dioxide,water and sunlight to make their own food,grow and release oxygen through photosynthesis. They're a huge part in keeping our air clean. The carbon becomes part of the plant. Plants that die and are buried may turn into fossil fuels made of carbon like coal and oil over millions of years. When humans burn fossil fuels, most carbon enters the atmosphere as carbon dioxide.
