How does penicillin kill bacteria? Penicillin augments the body's natural ability to enzymatically degrade bacterial peptidoglyc

an, causing the cells to lyse Penicillin targets a cross-linking reaction in cell wall manufacture. By blocking the enzyme responsible, penicillin stops the bacteria from producing new peptidoglycan. Penicillin targets muramic acid in the cell wall. By damaging a key component of the cross-linking reaction, the cell can't build a strong peptidoglycan mesh and quickly breaks apart. Penicillin damages the lipid membrane of bacterial cells by enzymatically removing peptidoglycan from the membrane's outer surface. The weakened cells quickly lyse.

Answer:

The correct answer is option c. By blocking the enzyme responsible, penicillin stops the bacteria from producing new peptidoglycan.

Explanation:

Penicillins are derived from Penicillium molds. These are a group of antibiotics, used in treating various types of bacterial infections such as urinary tract infections, respiratory tract infections, gastrointestinal infections etc.

These antibiotics also used in treating gonorrhoea, meningitis, pneumonia, syphilis, etc. These antibiotics stop the bacteria from producing new peptidoglycan that blocks the enzyme.

Describe how a plant cell is specialized for photosynthesis at
insens350 [35]

Answer:

In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle—the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules.

Is autism more common in a certain group of people?
Inessa [10]

Answer:

Explanation:

# Boys are four times more likely to be diagnosed with autism than girls.

# Most children were still being diagnosed after age 4, though autism can be reliably diagnosed as early as age 2.

# 31% of children with ASD have an intellectual disability (intelligence quotient [IQ] <70), 25% are in the borderline range (IQ 71–85), and 44% have IQ scores in the average to above average range (i.e., IQ >85).

# Autism affects all ethnic and socioeconomic groups.

# Minority groups tend to be diagnosed later and less often.

# Early intervention affords the best opportunity to support healthy development and deliver benefits across the lifespan.

# There is no medical detection for autism.

Complete the equation for photosynthesis.
lesya [120]

Answer: Equation for photosynthesis is carbon dioxide + water + sunlight→ Glucose + oxygen

In light dependent reactions, energy in form of solar energy is absorbed and converted to chemical energy.

Explanation: During photosynthesis, sunlight is absorbed by the light absorbing pigment called chlorophyll. The absorbed solar energy is converted into chemical energy using carbon dioxide and water as the starting materials with the release of oxygen. The equation is 6 CO2 + 6 H2O + solar energy --> C6H12O6 + 6O2.

Photosynthetic reactions are made up of two parts: the light dependent reactions and the carbon fixation reactions. In the light dependent reactions, chlorophyll and other photosynthetic pigments absorb light energy from the sun and conserve it as ATP and NADPH with a simultaneous release of oxygen. The carbon fixation reactions are driven by the products of the light dependent reactions.

Explain how a rise in carbon dioxide concentration in the atmosphere can decrease biodiversity.​
Zolol [24]
Elevated carbon dioxide levels may mitigate losses of biodiversity from nitrogen pollution. ... Rising levels of carbon dioxide may overheat the planet and cause other environmental problems, but fears that rising carbon dioxide levels could directly reduce plant biodiversity can be allayed, according to a new study.
